Hello,

I'm using a Philips webcam PCVC720/40 on an embedded platform with linux kernel 2.6.11. If I plug the webcam it is detected and the driver PWC registers it on /dev/video0. The problem is that I can't comunicate with the device, because if I try to read it, tapyng:

od /dev/video0

it returns:

pwc isoc_init() submit_urb 0 failed with error -12
pwc isoc_init() submit_urb 1 failed with error -12

the FAQ says that I have to remove EHCI and use UHCI only. Is there another way? bacuase I don't have UHCI but only EHCI (I'm using an embedded platform).

Thank you for any ideas.

Best regards,

Michele Nobis
