Dear list, I've been working on a simple test application where I grab video frames, in yuv from my Logitech Quickcam pro 9000 using v4l2. I'm getting the frames (although I haven;t decoded them yet) correctly. I'm using mmap for io. When I start my application, the LEDs of my cam turn on too. But when I press CTRL+C, and force my app to exit, the device disappears from /dev/video0 and my keyboard which is on the same usb bus stops working too. I'm now rebooting to enable my keyboard and webcam again. I'm new with v4l and wondering if someone knows about this problem or if someone has any pointers for me where I could look to figure out what's going on. I've been looking at /var/log/dmesg but couldn't find anything in there. When I press CTRL+C nothing is logged to dmesg.
