can something like this be done for linux? maybe a wrapper for lsusb. I just found https://github.com/doug-gilbert/lsucpd which adds PD and more.

thanks!
emaroMay 1, 2026
Pretty cool. What I don't understand is why both my USB@1 and USB@2 show the same connected devices. I'd expect to only see the respective devices. USB@1 is my USB-hub monitor, the other one is connected to my phone. Both show keyboard, etc. plus my phone as connected devices.
bkummelMay 1, 2026
Doesn't work for me. Says "No USB-C ports detected", although I'm pretty sure my monitor is connected via USB-C, and the monitor also has a built-in USB hub where my USB keyboard is connected to.

Wontfix for Intel Macbooks: https://github.com/darrylmorley/whatcable/issues/12

Seems the Intel southbridge isn't known to expose the needed info.

sleepingNomadMay 1, 2026
Hi, should be fixed now.

Not for me! Intel Mac Pro 7,1, Sequoia 15.7.3, running v0.4.7
aquirMay 1, 2026
Good stuff, but it's telling me that my USB-C Thunderbolt cable has been plugged in upside down but the connector handled this. I was not aware that you can plug in something into USB-C upside down!
justusthaneMay 1, 2026
I wasn't either (insomuch as I had never thought about it), but it makes sense if you think about it for a second. If you have one end plugged in one way, and the other end plugged in the other way, each individual wire is flipped from where it should be. The fact that you _can_ plug it in either way means that the device on one end needs to be capable of recognizing that and logically reversing it. Same as automatic crossover in Ethernet.

That's all the program is telling you. It doesn't matter that it's backwards, but technically it is.

regularfryMay 1, 2026
It's not always the case that the cable will correctly fix it. I think (hope?) any that any which didn't would be out of spec, but they exist...
justusthaneMay 1, 2026
It's the cable that is supposed to reverse itself and not the device? I'm not entirely sure I buy that - seems like it would add a lot of unnecessary complexity to every cable.
nheckerMay 1, 2026
The terminating device(s) are the ones that do the flipping, not the cable. You can take a cable that works either way between two high-end device, and then connect it to at least one low-end device and it will fail to connect for one of the two orientations.
jrmgMay 1, 2026
What does it mean to be ‘upside down’ if the connector handles both orientations?
hurfdurfMay 1, 2026

This has been fixed now, apologies.

This is actually one of the cost adders of USB3 USB-C devices. They need lane swapping ICs which are basically high speed analogue switches.
globular-toastMay 2, 2026
You can't. This software is leaking implementation details of USB-C and you really don't need to know this. I understand it's tempting to show everything, but the author should have exercised restraint here (this is assuming they were consciously involved at all, of course).
kmmbvnr_May 1, 2026
Could it be just a console utility?
captainblandMay 1, 2026
Yeah I like the sound of the functionality but I don't like the idea of it taking up menu bar space. Console utility would be good or even a gui that can be quickly launched through spotlight
piskovMay 1, 2026

You know you can close it? :-)

The 'plugged upside down' is weird for a USB-cable. Especially as that doesn't work. I tried plugging it 'the other way around' and it showed the same 'upside down' warning
AndroTuxMay 1, 2026
Everyone knows you have to flip the USB cable twice before it’s no longer upside down.
fuzzylightbulbMay 1, 2026
usb superposition. my favorite of the classic phenomena
BiteCode_devMay 1, 2026
Tangential, but LLT recently came out with their own lineup of USB-C cables guaranteed to be up to spec. And they have the main specs printed on each cable end, so you know what you grab.

That should be mandatory.

aphrozMay 1, 2026
You mean LTT ?
smusamashahMay 1, 2026

barbazooMay 1, 2026
I'll only buy them if they have gold connectors, those are the fastest. /s
ricardobeatMay 1, 2026
I remember seeing a recent analysis where the vast majority of cables from Amazon misreported their capabilities. Is this tool going to be able to catch those, or blindly report what the chip advertises?
NeywinyMay 1, 2026
I think for real cables the delta could also be explained by damage or just a bad plug-in attempt, so even if you're not trying to detect counterfeit cables it could be useful to know:

1. What does the host support

2. What does the cable support

3. What does the device support

4. What actually got negotiated

avidiaxMay 1, 2026
The tool can only tell you what the cable says. Detecting the gauge and composition of the wires in the cable is either destructive or requires temperature probes.

Detecting whether the signal characteristics are close enough to in-spec or not requires a speed test, perhaps, but that also doesn't necessarily mean the cable is the problem if such a test failed.

thenthenthenMay 2, 2026
This would be super to have! I do a lot of software defined radio work and the quality of USB (C) cables is pretty much a wild west. I needed some for a workshop and it was almost impossible to find a cable that didnt have crazy reflections and interference at all frequencies. I went through 6 different brands and vendors. In the end the cleanest signal came from an original Apple Type C cable (around 20usd). I am not sure if its because their shielding, differential pairs or signal integrity computation (iirc there is like a pretty beefy soc in the connector), or that I used it with an Apple Macbook. Some of the cables I found to perform badly were cut open, revealing missing shielding and none of them had twisted pairs.
AlifatiskMay 1, 2026
Any plans to support installations through Homebrew?
sleepingNomadMay 1, 2026
That's added.
sagacityMay 1, 2026
This is pretty nice, but why do a lot of Mac apps insist on living in the menu bar?
poisonborzMay 1, 2026
Making 1 click to access is faster than typing the app name in finder. Dock is usually full and used for different type of apps. Makes also constantly visible output possible with standard ui patterns.
UqWBcuFx6NV4rMay 1, 2026
OK, thanks. We understand what a menu bar is.

How is this conducive to the typical usage pattern of an app like this?

awakeasleepMay 1, 2026
Are you saying you wish this was a desktop app and you would just open it occasionally when curious?

If so, it feels like a needlessly indirect and combative way to go about it.

teh_klevMay 1, 2026
Why is it "combative"? Seems like a needlessly hyperbolic description of launching a desktop app.
krannerMay 1, 2026
For some reason the app supports a separate standalone window mode as well [0]. It's not clear why the developer took the trouble to support two different modes when the menubar mode doesn't seem to add anything (like a live-updating icon for throughput).

Well, I can think of one reason why it wasn't that much more trouble. François Chollet had a nice tweet [1] on why removing human cognitive friction is resulting in needless software complexity.

jaffeeMay 1, 2026
> removing human cognitive friction is resulting in needless software complexity

This is kind of a hilarious statement just on the surface. Isn't removing burden from humans the whole purpose of software? How can you call the complexity "needless"?!

(the actual tweet seems to go into a bit more detail around being incentivized to find good abstractions)

krannerMay 1, 2026
I think you're conflating the burden of creation with the burden of relevance, suitability, usability and usefulness of the created artifact. The more the person in charge is disengaged, the sloppier the output is likely to be.
hdndjsbbsMay 1, 2026
Making it trivial to generate software is making people turn their brains off. They don't think through the details and accept the "default" from an LLM which has no concern for the user experience.
wlonklyMay 2, 2026
> It's not clear why

People asked for it in these comments here and the developer added it.

krannerMay 2, 2026
Thanks, from the git log I see it was committed 20 minutes before my comment. I was going by the HN title and description and missed those comments.
lxgrMay 1, 2026
> Dock is usually full

My menu bar is also full and, unlike the Dock, I can’t resize it to fit more.

poisonborzMay 1, 2026
You can put it in a secondary onclick taskbar with Ice (similarly to Windows)
alexcrooxMay 1, 2026
Just a heads up Ice is abandoned and broken on upcoming versions of MacOS. I still need to look into an alternative

Thank you for posting this, I've been increasingly frustrated with ice recently and have been considering paying for bartender, now i won't.

Thaw is a fork of Ice which is maintained and woks on Tahoe.

https://github.com/stonerl/Thaw

lxgrMay 1, 2026
There's also Bartender, Hidden Bar etc., but they all come with some downsides.

I just don't get why Apple doesn't recognize this as a problem. Do the engineers working on macOS all have two of these 5:1 aspect ratio ultra wide monitors!?

xp84May 1, 2026
Worse - even if you have two, Apple just duplicates the menu bar on both screens.

Especially with the abomination that is The Notch, the menu bar has been overcrowded for years. No offense to OP. I’m talking about the 5 or so items I can’t get rid of in there.

pndyMay 2, 2026
Whenever I look at my partner's Macbook I'm having a flashbacks from Win9x/2000 times when tray area was filled up.

But Microsoft managed to deal with that issue - years ago. With XP they introduced collapsible tray area and later, it also become possible to rearrange icons.

Somehow for Apple the problem doesn't exist or they assume that their users will choose a 3rd party solution. Frankly, it's them who should provide the solution straight within the operating system. Especially when Apple computers revolve nowadays more around laptops which by definition have smaller display area.

efskapMay 2, 2026
Sure you can.

defaults -currentHost write -globalDomain NSStatusItemSpacing -int 2

defaults -currentHost write -globalDomain NSStatusItemSelectionPadding -int 2

Replace write with delete to undo.

SomeoneMay 1, 2026
And ‘every’ Mac developer thinks people will want to run their tool all the time.

For this kind of read-only tool, I doubt that’s the case. A regular application probably serves most users better.

Also, if you want users to have the option of permanently displaying this kind of info, a desktop widget (https://developer.apple.com/documentation/widgetkit) may be a better option than a menu bar item.

sgtMay 1, 2026
Exactly, this should just be a regular app with an optional menu bar option for those who want to switch it on.
sleepingNomadMay 1, 2026
I like this idea.
johanycMay 1, 2026
Spotlight exists. Typing is much faster than moving your cursor to a small target like a menu bar item.
mft_May 1, 2026
Agreed, especially for something like this that might get used a handful of times (I’m assuming most people don’t have myriad cables or want to check them regularly?)

The problem of course is that on my 14” screen the area to the right of the notch is already close to full and I don’t even have that many things there…

jrochkind1May 1, 2026
oh no you're right, my menu bar is full already.
sleepingNomadMay 1, 2026
It works for me, but I understand for others it might not. So, there's now a "Show in menu bar" toggle in Settings. Turn it off and WhatCable runs as a regular Dock app with a normal window instead.
_MicroftMay 2, 2026
Is it not rather useful in this particular case? You will see the reported capabilities whenever you plug in a cable. Or do people rather want to diagnose and label their cables just once?
sagacityMay 2, 2026
Sure, but do you diagnose cables so often that you need a permanent icon in the menu bar?

Following that logic, every application you use more than a handful of times should live there.

Anyway. I'm not trying to argue, I think this is a neat tool, but when the Windows tray got bloated with icons people used to complain about it.

denkmoonMay 1, 2026
I get that the connectors are identical but I find it odd that people find it so challenging. Thunderbolt is the thick and short cable. If it's not thick it's not gonna work well and if it's over a metre it's not gonna work well. cf my pile of thin long "basic" usb c cables.
conspMay 1, 2026
Thunderbolt 4 passive (over usb) is 0.8m in length, longer cables are active, up to two meters I think, so they do exist.
wallst07May 1, 2026
How do you define "thick" or "short" to a non-engineer/tech person? Relative to what exactly?
lostloginMay 1, 2026
Are you talking about cables?
wallst07May 1, 2026
Lol, maybe?
sgerenserMay 2, 2026
It comes with experience, you know it when you see it.
zimpenfishMay 1, 2026
Great, and what about non-Thunderbolt cables? How do I distinguish between power only, USB 2, USB 2+PD, and USB 3.2 cables? I've got a whole pile of cables that, without my Treedix tester, are indistinguishable re: functionality and support.
gedyMay 1, 2026
I like the idea and thanks for sharing, but I do think folks who vibe code or use Claude should take their time using, testing, and improving app before rushing to share. This was pushed/deved like 2 hours ago
xandriusMay 1, 2026
Just because it got pushed 2h ago it doesn't mean they didn't test it on their end.
sleepingNomadMay 1, 2026
I did indeed test it. Had the idea, and wanted to get it going.
LordGreyMay 1, 2026
And it's been updated, with full releases, many times since.

I like this tool, but I agree that it was rushed and it is still being rushed. I urge the developer to slow down and get it right.

literalAardvarkMay 1, 2026
This isn't an air traffic control system though.

Shipping early is an entirely valid dev strategy.

theanonymousoneMay 1, 2026
I would like to ask an LLM to rewrite it as Python CLI script. Is it even possible, or some Swift-only functionality is necessary?

P.S. Some time ago I learnt through HN of a one-line command in macOS which revealed the power (Wattage) of the connected charger. Can't find it now, but it was very useful.

krelasMay 1, 2026
`system_profiler SPPowerDataType | grep "Wattage"`?
theanonymousoneMay 1, 2026
Yes, something like this. Thanks!
nheckerMay 1, 2026
Python script that Claude Code wrote and I tweaked for peeking at marked USB-C cables: https://github.com/nhecker/usb-e-marker

Gist of random (human-written) power-related commands to peek at random power info: https://gist.github.com/nhecker/8e850773ff229724ce361967cc22...

For your last point, you're probably looking for something like `ioreg -raw0 -c AppleSmartBattery | plutil -extract 0.PowerTelemetryData.SystemPowerIn raw -` (The source for that last command is from the above gist: https://gist.github.com/nhecker/8e850773ff229724ce361967cc22... ) Or maybe `pmset -g ac | head -n3` is helpful, too. HTH.

thiagoperesMay 1, 2026
I am definitely gonna contribute or fork to create an open leaderboard of cable brands and quality :D
j16sdizMay 1, 2026
It won't tell you the _quality_

It just tell you want the e-marker said.

zimpenfishMay 1, 2026
> It just tell you want the e-marker said.

Which isn't helpful if the cable has no e-marker.

rupxMay 1, 2026
Yep, the e-marker can effectively report whatever.

You'd need proper hardware capable of testing bandwidth, power, noise, etc, which is prohibitively expensive.

sleepingNomadMay 1, 2026
That's a great idea.
thenthenthenMay 2, 2026
I dont know how they do it, but the original Apple Type C cable is GREAT. I use it for software defined radio stuff, where your usb cable can start to act as an antenna and causing interference and reflections. I tested about 6 different brands and vendors and these gave the cleanest signal. Theyre also pretty pricy sadly. Not sure about the speeds and pd, but suspect it should be fine…
mp0rtaMay 1, 2026
Great project. It would be even better if it supported platforms other than Mac.

pimeysMay 1, 2026
Cool. Just want to chime in that I wanted to see how quickly GPT-5.5 can turn this into a KDE Plasma 6 Plasmoid. Took about 10 minutes and two dollars, and now I have a nice QML app showing the same information in my taskbar.

Just wanted to say this because I feel it's really crazy that I can just do this today...

geordieboozerMay 1, 2026
To save me 10 mins and $2, is this posted to GitHub somewhere?
rustyhancockMay 1, 2026
Absolutely this is worth packaging for KDE.

Although I imagine if you don't have the motivation to make it in the first place, you likely don't have the motivation to package it.

pimeysMay 1, 2026
I feel like this is so lazy bothering maintainers for it is not great.
marmaramaMay 1, 2026
No need to bother maintainers, just package it up and upload it to the KDE store as a Plasma extension. Then it can appear for download in "Get New Widgets" in Plasma edit mode. Plenty of "lazy" widgets in there.
techwizrdMay 1, 2026
I am happy to package it and port it for Gtk/GNOME today.

TeMPOraLMay 2, 2026
Yes, as long as there are humans reviewing and quality-gating the outputs at every stage.

Otherwise, it's just a very long exoprosthetic digestive tract.

May Day - like labour day in Canada/USA... but on the first of May
xp84May 1, 2026
I would argue nothing about American Labor Day has anything to do with labor at all. Honestly we should just rename it “Summer’s End” because there is literally no theme. The ad flyers for the sales on that weekend have, if any perceivable theme at all, red, white and blue / Stars and Stripes for some reason. It’s traditional that school starts the day after it, but in many places that’s been dragged several weeks sooner into August for some sick reason.

We just don’t even have any holiday that honors labor, laborers, or labor unions.

TeMPOraLMay 2, 2026
> I would argue nothing about American Labor Day has anything to do with labor at all. Honestly we should just rename it “Summer’s End” because there is literally no theme.

Isn't that true of most holidays pretty much anywhere in the West these days? Sure, there's Christmas and Halloween and Easter that have specific themes, but excepting deeply-religious communities who practice associated traditions, they're as meaningful as cosmetic items in free-to-play games. But every country has a bunch of other holidays that most people don't know or care about much beyond knowing it's a day off.

hdndjsbbsMay 1, 2026
It's May Day, which is a labour holiday everywhere except North America commemorating the Haymarket Affair when American police brutally repressed striking workers .

In North America we have Labor Day in September to distance it from the historical associations with actual organizing and police brutality.

reaperducerMay 1, 2026
Still widely noted in Chicago, where the Haymarket riot took place. There's even a very well-attended reenactment every year.

North America is a big place. Generalizations always fail.

prmoustacheMay 1, 2026
You do know that no sea/ocean has split the continent and that Mexico is still in North America right?

1st of may is festive day in Mexico.

Props to @sleepingNomad here, who has done 16 releases in the last 7 hours, incorporating feedback from HN on the fly!

* Don't like menubar apps? you you can run it as a normal app

* Don't like GUIs? Now you can run it on the command line

Just look at that Changelog:

Clean execution. The "tiny menu bar app" framing is exactly where I'm trying to land my own scope right now.

What was the hardest thing you cut to keep it tiny? I keep adding "one more useful thing" and have to talk myself down.

tonymetMay 1, 2026
awesome utility . I purchased a $50 usb cable inspector on Ali express because usb-c compatibility is atrocious. there are dozens of protocols, (data, multiple PD, EPR, various wire gauges, various pinouts connected etc).

USB c is really just a connector standard, but vendors sell the cables as if it’s a cable standard. It’s a failure of the USB standards group to establish conduductor, pinout, shielding and protocol standards for consumers to understand.

There should be color and markings on USB C cables similar to resistors so you can immediately tell WTF the cable is capable of before and during use.

archagonMay 1, 2026
I'm curious how the SPI to do this (e.g. `IOPortTransportComponentCCUSBPDSOP`) was discovered. There was nary a mention of it anywhere prior to release. Even Claude has to latch on to something. Always wondered if there was some way to read emarker data through some buried framework, but wasn't sure how to find it.

I don't think I can abide running vibe-coded software, but maybe I'll make a hand-coded fork now that the SPI is exposed. (Assuming it works correctly.)

dhosekMay 1, 2026
This is something that I’ve wanted for quite a while. I have lots of mystery USB-C cables that it would be nice to be able to label with their capabilities. Now I can.
gigatexalMay 1, 2026
very, very cool thanks for making this.
NelsonMinarMay 1, 2026
This reminds me ChromeOS has some USB-C cable identification superpowers: https://www.reddit.com/r/UsbCHardware/comments/1pyojjd/comme...

Not sure if it's using the same thing this MacOS thing is doing. In the link the author explains that the cable e-Marker contains a "Discover Identity" message that you can read and display in ChromeOS. Most ordinary Windows hardware can't read it because of BIOS limitations, but Chromebooks can. I'm guessing Macs can too.

Is it also possible to read the e-marker on non-Apple devices? Linux or windows?

This would be so useful...

Awesome! It handles my kinda complicated setup with docking station, USB and DisplayPort switches pretty well.

Interesting - do we know why that api is not allowed? I see no reason, especially if it would also require runtime permission from user.
