Hello,
According to Stefan;
https://lists.berlios.de/pipermail/linux-uvc-devel/2007-March/001476.html
.. the reset functionality is a part of a patch that is applied against
the UVC Module that get compiled and included in the kernel. From
my reading of the code, it automatically resets the USB device (without
user intervention). Thus no command is required.
But, to my understanding, this patch is not included by default in UVC.
