Hi everybody First of all, great thanks to uvc driver developers for great work.
I try to use driver with Logitech QuickCam 5000 and have the following situation: Camera is found and initialized by driver. Everything works wonderfull, except occasional lockups with message "uvcvideo: Failed to query (1) UVC control 4 (unit 1) : -110.". I use "reset patch" and it works (I can get picture from camera after reset), but I cannot use camera's controls after reset. When I try to change any control (for example brightness or contrast) nothing happens. More interesting, when I unplug and replug the camera, I cannot change controls too! And the most interesting thing - controls stay unchangeable after reboot! I found two ways to fix this situation: 1. Poweroff the machine, unplug power cord, replug it and turn the power on. Everything works 2. Build ehci_hcd as module, rmmod it and modprobe again. Everything works too. So, my question is - is there any way to reset ehci without reinserting module? I know, that usb_reset_device() resets device and power state at given port. Is there any way to do something similar with hole host controller? Sorry for my bad English.
