The 'reset patch' is just a small piece of code that solve USB hardware bug with some Logitech Webcam.
Anyway, test was made with and without the reset patch. The reset patch just allow me to not reboot my PC after aMsn exit on error. Unloading and reloading the uvcvideo module doesn't seem to work with my cam without the reset patch! As I say in previous email, test with aMsn are made after a check with luvcview that the cam is ok. If it is a bug with the driver, luvcview and ekiga should not work also! But they work well! The reset patch can be found in the uvcvideo mailing list archive at http://lists.berlios.de/pipermail/linux-uvc-devel/2007-March/001476.html If I have some time, I'll re-read the patch added by revision 8464 in aMsn and compare it with luvcview source code.
