[linux-uvc-devel] Logitech StreamCam

Hi,

I found a different thread on this camera from a month ago (
https://sourceforge.net/p/linux-uvc/mailman/message/37001224/)
but here's my take on the problem. If you have any pointers on where I
should be looking at next, let me know

I've just received this camera today and I'm trying to use it on my Ubuntu
20.04 machine.
When I first tried to use it, it worked at 640x480 and 30fps.
However whenever I tried to raise the resolution (this cam is supposed to
work at FullHD at 60fps) I got a blank screen.
After a while the camera didn't seem to work at all so I rebooted my
machine and tried to do a video chat call.
People could see me. The camera seemed to be working at 640x480 but the mic
wasn't working. The other person could only hear noise.

If I keep the resolution low I can get the camera to work once. After it
works it spits out an error:

[10066.231871] usb 4-1: reset SuperSpeed Gen 1 USB device number 3 using
xhci_hcd
[10093.078665] xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled

1b000000 02038000

and after that, unplugging and replugging the camera will return

# errno 110
ETIMEDOUT 110 Connection timed out

This only gets fixed by rebooting the pc.

the modules being loaded by the camera are:

videobuf2_vmalloc
videobuf2_v4l2
tw5864
uvcvideo

It also seems to increase the "used" count for snd and snd_usb_audio

When I connect the device, this is what I'm getting from dmesg:
