I got that feeling that things won't be easy, but M$ webcam put this
right into 'hardcore entertainment' category. Marked AO for Adult Only.
Viewer discretion is advised.

And that means it's time to try a magic trick. You need to be root, or
it won't work.

modprobe uvcvideo

echo 045e 00f8 > /sys/module/uvcvideo/drivers/usb\:uvcvideo/new_id

ls -al /dev/video*

Known side effect can include (but not limited to):

- dizziness
- webcam explosions
- kernel panics
- frozen food disappearance

The reason for this is [1]. If the link is to be believed - USB device
with ID 045e:00f8 should be supported by uvcvideo (an in-tree kernel
module). If you're lucky, the only thing that's missing there is a
declaration for aforementioned USB ID.

If the trick does not work I suggest to try the kernel from the
backports.
