AMD-ucode issue?

W54J04S07T · 2019-05-04 15:29:59

I get this on boot up on a AMD2700 based system with
ASUS x470 MB and the usb cam goes undetected..

usb usb5-port1: Cannot enable. Maybe the USB cable is bad?

Previously, I installed amd-ucode and did the usual mkinitcpio
followed by the recommended grub-mkconfig to insert the ucode
on boot.

The above message disappeared... and the system could see the
installed usb camera. With the most recent ucode update along with
the mkinitcpio / grub-mkconfig commands the problem re-appeared
and I can't seem to fix it. The major changes in the update would
be recent ucode, systemd and kernel updates. Any pointers on getting
at this problem?

Additional info;

I downgraded ucode to the previous version that worked, no effect.

Updated ucode back to current and installed most recent kernels,
with no effect.

Using most current updates, switched to LTS kernel, again with no
effect.

kernel : usb usb5-port1: Cannot enable. Maybe the USB cable is bad?

and kernel still "cannot enumerate device".

Doubt that's due to microcode updating.

Rename to something like "usb camera not working anymore" .

Post lsusb , lsusb -t and dmesg|tail with the camera unplugged .
Then plugin the camera and post those outputs again.

As this problem was solved by inserting amd microcode
( as recommended in numerous posts on this issue )
and then reappeared some time later after a microcode
update, I'm sticking to my suspicions re microcode/
systemd /kernel...

What happens if you uninstall amd-ucode?

W54J04S07T · 2019-05-07 18:43:12

No diff. Installing amd-ucode is what initially solved the problem.

Also, I verified the cable isn't bad, and when I reboot with the cable disconnected
"at the webcams port" this part...

...disappears... only to reappear as soon as I reconnect the cable to the cam port.

BTW, this webcam is an integrated into the display unit type deal from around 8 years ago.
asus model vk278q.

Buddlespit · 2019-05-07 19:40:13

I'm going to go with Lone_Wolf on this, I don't think it's the microcode. It didn't work prior to microcode being installed, worked for a short time with microcode installed, won't work with version of microcode that did work at one time. Sounds like a hardware issue, to be honest with you brother.

Do you have a spare webcam floating about that you can plug into bus 5, port 1? Does bus 5, port 1 work if something else is plugged in? Does your webcam work if it's plugged into a different usb port?

Do you have linux-firmware installed?

W54J04S07T · 2019-05-07 21:01:52

Just tested now.
Webcam was plugged into USB3.1 Gen 1 port at back.
No action.
Plugged webcam into USB3.1 Gen 2 port... WORKING!
And yes, a USB drive plugged into the original Gen 1 port
worked fine as well.

Rebooted.
Problem returned... this time on bus3 port 1 ( Gen 2 device )... and no webcam
unplug/plug webcam did not return functionality either.

Originally problem was solved by installing amd-ucode.
But I suppose it could be a race condition or something
similar in systemd /kernel /ucode.

Just throwing it out there but have you tried to connect it to a different machine or boot a different OS to see if it has the same issue?
It sounds very much like the device itself is probably broken. (or maybe, as the error msg says, it really is a bad cable)

On the theory that this H/W config is pretty much the
go to these days, and no one else seems to be in this
pickle, I started looking around in the BIOS.

In the BIOS, I discovered that IOMMU was disabled,
so I enabled it. Powered down everything ( literally )
went away , came back, powered up and Bingo everything
is working including the Cam.

Rebooted, just to make sure it wasn't a fluke, and everything
is still working. Tomorrow, I'll do a full sys upgrade and see
if my luck is holding.

Omar007 · 2019-05-08 20:15:12

I suppose you have no clue what IOMMU even is, nor even care so I'm not going to bother explaining.
Just want to leave you with one word: unrelated.

Anyway, from my perspective this is going nowhere. The problem is clearly with the system/kernel/systemd/bios/anything-thats-not-the-device and the device is flawless. ¯\_(ツ)_/¯
