Hello,
It seems the USB product ID for g_webcam usb device gadget is incorrectly used
from EEM gadget "Ethernet Emulation Model". So "webcam" device has a confusing
description in lsusb:
1d6b:0102 Linux Foundation EEM Gadget
I would change it to 0x0106, which is a next unassigned value (according to
http://www.linux-usb.org/usb.ids). Does this step require some official
communication with the holder of VID (Linux Foundation)? Or all it takes is
just to send patch to the kernel and to the usb.ids database?
I know it is only a cosmetic change on a legacy driver, but I assume it would
be better to have some default value for configfs API than to borrow a PID from
a whole different gadget.
Change in question would be something like this (I will send a proper patch
after RFC):
Fixing USB Product ID for UVC gadget (used from Ethernet Emulation Model) and
changing it to new one.
