Hello 

I'm having trouble with a Creative WebCam Live! Pro, usb id 041e:4038 "Creative Technology, Ltd ORITE CCD 
Webcam [PC370R]" 
This device is supposed to be "supported" but is marked as "untested" at http://gkall.hobby.nl/sq930x.html
Apparently it works up to the point where sq930x fails with this message : gspca_sq930x: reg_r 001f failed -32 

See a more complete log here : http://pastebin.com/yY4THaFN 

The kernel I'm using is a custom made 3.9.3. 
What other information do you need to debug this issue ? What options must I activate in the kernel in order to 
get a more verbose syslog regarding this component ? 
Is there any hope at all for this device, as there seems to be no information available at all from Creative or 
any other source ? 

Sincerely, 
  =^.^=

Hello again

I've just compiled a new 3.9.7 kernel and applied a patch suggested by hverkuil on #v4l : I removed the comments around reg_w(gspca_dev, SQ930_CTRL_RESET, 0x0000); in ./drivers/media/usb/gspca/sq930x.c at line 839
This is what I get now :
Jun 21 18:19:31 elnath kernel: [    6.587245] gspca_sq930x: reg_w 001e 0000 failed -110

Log extract : http://pastebin.com/ay74d5YB

If reg_r() and reg_w fail, it means that usb_control_msg() returns those -32 and -110. How do I debug that ?
