Description Pablo Bender 2016-04-29 23:51:25 UTC 
Description of problem:

The integrated usb webcam (Chicony hd - 04f2:b337 ) not detected anymore.
A few weeks (maybe 1 or 2 months) it was working.

After each released update I have tested to know if the cam back to work.

I performed dnf update today.

Before the update (yesterday):
- cam present in dmesg output
- cam not listed on lsusb output
- no /dev/video0 device

After the update (today):
- cam not present in dmesg output
- cam still not listed on lsusb output
- /dev/video0 device still out

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. boot the system
2. ensure that uvcvideo driver was loaded
3. open a program that read from webcam (eg: cheese or camorama)

Actual results:
missing /dev/video0 device
cam not listed with lsusb or usb-devices


Expected results:
a functional /dev/video0 device

Additional info:

My hardware is an Acer Aspire V3-571

What's the last kernel version where this worked? If you boot into that kernel again do you see the webcam?
Comment 2 Pablo Bender 2016-05-03 01:14:46 UTC 
Unfortunately I don't remember the version where this worked.

The kernels available on my system are:

vmlinuz-0-rescue-e61a885953004c3bb1d9b0eed77b6d58
vmlinuz-4.4.6-301.fc23.x86_64
vmlinuz-4.4.7-300.fc23.x86_64
vmlinuz-4.4.8-300.fc23.x86_64

but, the cam stop to work before.
