Hello, I have problem with UVC webcam. It's Genius Facecam 1000. I would like to use it with mjpg-streamer. Before this model, I had Facecam 1320, but it wasn't mjpeg capable, so mjpg-streamer had to do jpeg compresion and it was quite slow. Facecam 1000 can provide mjpg stream by itself and it works great on x86, but it doesn't work on ARM. To exclude problem in mjpg-streamer I compiled v4l capture example (http://v4l2spec.bytesex.org/spec-single/v4l2.html#CAPTURE-EXAMPLE) and it's same - works on x86 a not on ARM. On embedded platform I'm using AT91SAM9260 (Olimex kit L9260) which has USB2.0, but only full-speed - is it problem? I don't think so - previous webcam works great. On x86 I use kernel 2.6.35 and glibc. On ARM there is kernel 2.6.33.7.2-rt30 and uClibc. v4l example fails with this error: VIDIOC_STREAMON error 5, Input/output error webcam is detected correctly: [ 2042.100000] usb 1-1: new full speed USB device using at91_ohci and address 3 [ 2042.290000] usb 1-1: New USB device found, idVendor=0458, idProduct=707e [ 2042.290000] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2042.310000] usb 1-1: Product: FaceCam 1000 [ 2042.320000] usb 1-1: Manufacturer: KYE SYSTEMS CORP.
