Version-Release number of selected component (if applicable): kernel.x86_64 3.6.10-2.fc17 How reproducible: Always Steps to Reproduce: 1. Attach the webcam to the USB 2. Check the kernel message and see the "recv_control_msg error -32 req 04 val 1700" error 3. start cheese 4. Check the resulting picture Actual results: [gert@jupiter tmp]$ dmesg| grep -i pwc [ 15.365755] pwc: Philips PCVC675K (Vesta) USB webcam detected. [ 15.829852] pwc: recv_control_msg error -32 req 04 val 1700 [ 15.968912] pwc: Registered as video0. [ 15.968953] input: PWC snapshot button as /devices/pci0000:00/0000:00:1d.2/usb8/8-1/input/input13 [gert@jupiter tmp]$ See attached picture. Expected results: No error message in the kernel log and a decent picture Additional info:
Just tried the webcam on my old PC (using an old Fedora version) and there also the picture is garbage. So, it looks like the webcam hardware is broken. The kernel error message does not occur there, that seems to be an unrelated driver problem/feature. However since my HW appears to be broken, I can test if this is a problem or not.
