What is the output of lsusb? --- Original Message ----- From: Justin Piszcz <jpiszcz@...idpixels.com> To: linux-kernel@...r.kernel.org Cc: linux-uvc-devel@...ts.berlios.de Sent: Tue, 03 Jan 2012 06:21:02 -0800 (PST) Subject: [Linux-uvc-devel] 3.1.5: uvcvideo: Failed to resubmit video URB (-27). Hello, Using an Acer 7551-7442 here with the following built-in webcam: Bus 002 Device 004: ID 0402:9665 ALi Corp. Gateway Webcam It seems motion locks up every day or so and I see this in the kernel logs: [378982.724053] uvcvideo: Failed to resubmit video URB (-27). [378982.724066] uvcvideo: Failed to resubmit video URB (-27). [378982.724079] uvcvideo: Failed to resubmit video URB (-27). [378982.724090] uvcvideo: Failed to resubmit video URB (-27). [378982.724101] uvcvideo: Failed to resubmit video URB (-27). [489148.723367] uvcvideo: Failed to resubmit video URB (-27). [489148.723379] uvcvideo: Failed to resubmit video URB (-27). [489148.723391] uvcvideo: Failed to resubmit video URB (-27). [489148.723403] uvcvideo: Failed to resubmit video URB (-27). [489148.723414] uvcvideo: Failed to resubmit video URB (-27). If I restart motion, it will usually start working again, I do not have this problem on other (retail) Logitech webcams, was curious if this a bug with the webcam (quirk?) or a problem in uvcvideo? The camera is built-into the laptop screen at the top in the middle. lsusb verbose: Bus 002 Device 004: ID 0402:9665 ALi Corp.
