USB issues in fedora-27 ("can't get device qualifier: Resource temporarily unavailable") not happening when booted into CentOS-6.2, same hardware

[Tom Hodder]

Hi All,

I've been having a bunch of trouble with the USB ports on my desktop, in
particular the webcam doesn't work and there are lots of errors in the
output <https://paste.fedoraproject.org/paste/qYxQ2rH-tlsE8pJqWz442w>
of *"lsusb
-v"* when I try to debug.  (I get the "can't get device qualifier: Resource
temporarily unavailable" errors, whether the webcam is plugged in or not,
which seems to eliminate the webcam itself as the source of the problem)

On the positive side, a usb keyboard, mouse and USB sticks seem to work ok.
The hardware is a Supermicro SuperWorkstation 7037A-i
<https://www.supermicro.com/products/system/tower/7037/sys-7037a-i.cfm>;,
with an X9dai motherboard
<https://www.supermicro.com/products/motherboard/xeon/c600/x9dai.cfm>;.

I assumed the problem was hardware related and raised a ticket with
supermicro. They asked me to test the machine using a supported OS, and the
nearest to fedora-27 was CentOS 6.2 (compatibility matrix
<https://www.supermicro.com/support/resources/OS/C602_listing2.cfm>). So
today I booted into Centos-6.2. To my surprise there were no errors in
the "lsusb
-v" output <https://paste.fedoraproject.org/paste/yVFlRYGi9m4ZCt9PZPF3Gg>;,
no errors in dmesg or syslog, and the webcam worked fine.

This seems to suggest it's not a hardware problem, but some difference in
the drivers. I am pretty sure the usb/webcam used to work, but that's going
back a few versions of fedora, and probably 3/4 years.

Any ideas on what might be causing this?

Many Thanks,
Tom

The error above is being reported by the uvcvideo module which is part of the
kernel.  For informational and debugging information the first thing I would do is
determine what kernel version is in used for Centos 6.2  v.s. F27.  I'm pretty sure
they are quite different. 

Then, I would also check the actual make/model of the webcam and see if there have
been any firmware updates to the camera.

Doing some web searches show that some user's webcams have shown the errors above and
have been *fixed* by kernel upgrades.  I've not seen where a camera ceased to work
after an upgrade but that doesn't mean it won't happen if it is actually a
firmware
issue in the camera itself.

As I mentioned above you should find the kernel version of CentOS 6.2 and potentially
boot a live Fedora with a similar kernel.

The fedora box is;
$ uname -r
*4.15.13-300*.fc27.x86_64

and the centos 6.2 is reporting;
*2.6.32-220*.el6.x86_64

I am getting those errors ("can't get device qualifier: Resource
temporarily unavailable") , whether the webcam is plugged in or not, which
seems to be a more fundamental problem. I only noticed it when trying to
get this particular webcam working.

I booted a fedora-15 liveCD (kernel 2.6.38.6-26.rc1.fc15.x86_64), and I am
not seeing any errors (Resource temporarily unavailable ), but none of the
webcams I tried work (I tried 3, 2 of which work correctly on f-27 on this
hardware)

I guess I am most concerned about the (Resource temporarily unavailable )
which would seem to be separate from the webcam issue, lsusb has only the
mouse and the keyboard....

...no webcam plugged in .... But still lots of errors in the output;

# lsusb -v  2>&1  | grep -C2  "Resource temporarily unavailable"
     bAlternateSetting       0
     bNumEndpoints           1
     bInterfaceClass         3 Human Interface Dcan't get device
qualifier: Resource
temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
can't get debug descriptor: Resource temporarily unavailable
...


I've tried swapping out the mouse and they keyboard with others, but those
errors remain..

So I've got a new webcam which is working, and I'm happy to scrap that old
webcam as broken, but I'd like to fix those errors that occur in the lsusb
output....

Cheers,
Tom

Good that you now have a working webcam.  Not all webcams work on linux.

Don't worry about those messages.  Every single one of my systems all get those
messages for various devices.  And all my devices which includes a keyboard, mouse,
bluetooth adapter, 2 Wifi adapters, and a USB headset work just fine.
