I need to know:
Where to go for support on gspca_vicam module ?
What is error code -110 mean with variable "FF"?
Anyone Know where is gspca source code?? (gspca_vicam)

Thanks for any help

Which version of Knoppix do you use?

Do you have any other Knoppix version you could try out?


Then loaded firmware.fw to /lib/firmware/vicam folder Have you installed a missing firmware file?

Have you installed a missing firmware file?

Will try other live Knoppix Live cd, and yes fw installed i.e. no -2 error.. can you confirm error code -110 is a timeout??

Anyone Know where is gspca source code?? (gspca_vicam)You can find the source code for vicam.c (http://lxr.linux.no/#linux+v3.4.4/drivers/media/video/gspca/vicam.c) at lxr.linux.no (the Linux Cross Reference)

The error code -110 is the return value of the function usb_control_msg. You can find its source code in message.c (http://lxr.linux.no/#linux+v3.4.4/drivers/usb/core/message.c).

Yes the Vicam Author, Hans de Goede, verifed the FF as Firmware load request and code -110 is a time out.
I did download Knoppix 7.xx+ Kernel 3.4.4 #14 SMP with the same results, i.e Formware load timeout.
I then fired up old debain Lenny where the Vicam firmware would load and have /dev/vide0 active, but Dmesg complained of control problems accessing the camera, i.e no led light at all!. I did a compare on both firmwares and they are exact no differences. I suspect something broke that firmware load from kernel 2.6-26-2 till 3.4.4. Now that I have a link to Gspca source code I can tinker with it. Hopefully more info to follow!
Thanks for all your help. If you have any other thoughts please post them.

Got it working , Used a Ubuntu Lucid .deb V4l Media-install package with updated V4l from GIT Tree. Looks like there were changes in poll.h and gspca.c and two firmware's , firmware.fw and firmware.H16. Thanks for all the help.
