V4L/DVB (13991): gspca_mr973010a: Fix cif type 1 cameras not streaming on UHCI controllers
commit 70136081fc67ea77d849f86fa323e5773c8e40ea upstream.
If you read the mail to Oliver Neukum on the linux-usb list, then you know
that I found a cure for the mysterious problem that the MR97310a CIF "type
1" cameras have been freezing up and refusing to stream if hooked up to a
machine with a UHCI controller.
Namely, the cure is that if the camera is an mr97310a CIF type 1 camera, you
have to send it 0xa0, 0x00. Somehow, this is a timing reset command, or
such. It un-blocks whatever was previously stopping the CIF type 1 cameras
from working on the UHCI-based machines.
