I haven't tested beyond that. I'm sure it didn't happen in 2.6.29. If I run "xawtv" and then suspend, it stops working on resume; the xawtv display goes black and the camera LED stays off. When I close xawtv, the LED blinks on then off again. If I then try to run xawtv again, it works fine. In dmesg (after resume) I see [ 562.884298] usb 1-8: type resume [ 562.990014] usb 1-8: reset high speed USB device using ehci_hcd and address 3 [ 563.665921] restoring control 00000000-0000-0000-0000-000000000101/0/2 [ 563.665935] restoring control 00000000-0000-0000-0000-000000000101/1/3 [ 563.665948] restoring control 00000000-0000-0000-0000-000000000101/3/7 [ 563.666412] uvcvideo 1-8:1.1: reset_resume error -12 Thanks in advance Alan
