Hi Acelan Kao,

An other guy with the 405b said that all modes were correct but 640x
and 320x upside down.

Looking at the .inf of the ms-win driver, it seems that the Mirror and
Vertical controls exist for the mi1310_soc sensor. May you change them
on ms-win? If yes, may you do a snoop to know which registers do the
job? Then, in the vc032x subdriver, only the set h/v flip had to be
inverted for the 2 webcam types.

Otherwise, I compared the sequences of the ms-win files C0130Dev.inf
(041e:405b) and usbvm323.inf (17ef:4802). The bridge sequences are
close enough, but the sensors sequences are completely different, as if
the sensors were different! So, it is not easy to find how the image
may be upside down...

BTW, I can't read your binary USB snoop. Have you any tool to read it
or may you send me a more readable version?

Best regards.
