[Spca50x-devs] gspca_vc032x: Sensor MI1320 in Samsung Q1 Ultra not working

Hello everyone,

I've installed the latest & greatest v4l drivers from
http://linuxtv.org/hg/~jfrancois/gspca/ and tried to use the camera on a
Samsung Q1 Ultra with them. The camera reports as 

Bus 001 Device 005: ID 0ac8:c301 Z-Star Microelectronics Corp.

and the gspca_vc032x driver recognizes it - dmesg shows:

[  703.298585] Linux video capture interface: v2.00
[  703.313857] gspca: main v2.7.0 registered
[  703.321625] gspca: probing 0ac8:c301
[  703.322554] vc032x: check sensor header 20
[  703.509321] vc032x: Sensor ID 148c (14)
[  703.509334] vc032x: Find Sensor MI1320_SOC
[  703.511699] gspca: probe ok
[  703.511764] usbcore: registered new interface driver vc032x
[  703.511775] vc032x: registered

However, no video tool works. cheese always reports "libv4l2: error
dequeuing buf: Input/output error" and the svv tool from the linuxtv
website just shows a green screen, nothing else. At one point, I've also
seen an error message in the log along the lines of "frame overflow
616416 > 614400".

Does anybody have a hint for me how to fix this?

Thanks, Yours, Florian
