[Folkert van Heusden <folkert@vanheusden.com>]

Package: linux-headers-2.6.22-2-686
Version: 2.6.22-4
Severity: normal


usb occasionally goes into EIO returning loop for VIDIOC_DQBUF

this happens while running 'motion' on a philips webcam on an usb bus with only 1 device
folkert@gateway:~$ lsusb
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 001 Device 002: ID 0471:0311 Philips PCVC740K ToUcam Pro [pwc]
Bus 001 Device 001: ID 0000:0000

e.g.:
[1] v4l2_next: VIDIOC_DQBUF: EIO (s->pframe 0)
[1] v4l2_next: VIDIOC_DQBUF: EIO (s->pframe 1)
[1] v4l2_next: VIDIOC_DQBUF: EIO (s->pframe 0)

what 'solves' the problem is closing and re-opening (e.g. restarting the process) the device
