Hello,
I’ve recently noticed a problem with Modecom Venus and A4Tech PK-333E webcams.
Both can be put into a “bad state” in which they refuse to do anything until
they’re reconnected to the usb port. The test case is simple:

Hello,
I'm sorry for another mail. It works with quirks 128 and uncompressed

Hello again,
now I discovered, that it's possible to change module parameters even
if they are compiled in kernel... So I did:
echo 2 > /sys/module/uvcvideo/parameters/quirks
And v4l example now ends like this:
VIDIOC_S_FMT error 28, No space left on device
Error "No space left" indicates prob
Hello,
I have problem with UVC webcam. It's Genius Facecam 1000. I would like
to use it with mjpg-streamer. Before this model, I had Facecam 1320,
but it wasn't mjpeg capable, so mjpg-streamer had to do jpeg
compresion and it was quite slow. Facecam 1000 can provide mjpg stream
by itself and it wo

Hi,
Do you mean the dmesg output ?
A full dmesg is included in this address :
http://pastebin.com/8XU619Uk
Not in all suspend/hibernate the problem comes, only in some of them
and this included dmesg output is just after a non working case of

I also have found this in `/var/log/mes

Hi,
After suspend/resume, I have my webcam no more working.
The /dev/video0 file still exist, but the webcam won't be used until I do this :
rmmod uvcvideo
modprobe uvcvideo
(2.6.31.8-0.1)
This is may be caused by a bug somewhere.
These are more information about my hardware :

Hi Acelan Kao,
I got news from a person who has the sensor mi1320_soc and had a
vertical flip problem. She found that the sensor register 0x20 sets the
image flips: bit 0 = vertical, bit 1 = horizontal.
Comparing the sequences of the mi1310_soc, the bit 0 is inverted in the
sxga (0x0303 instead o

Dear Jean-Francois,
I use "Lenovo WebCam Center" and "Dorgem" to do the webcam preview
function, there are the following resolution settings
160x120
176x144
320x240
352x288
640x480
Do you need all the resolutions logs?
I try to use "Device Monitoring Studio" to log the USB traffic this time.
