Hi all, I have buy new webcam Trust WB-1400T, connected to my Fedora and got very dark picture with probably bad whitebalance, while on windows, result is much better with the same device.

I tried:

1) HW check, verified - running OK
2) checked, if HW is supported. it is by driver gspca_pac207 with 5 stars

3) dmesg:

Any suggestions please ? I'm out of ideas (for sure I also tried to adjust camera using v4l)

Cheers

the cammera is detected quite differently:

it should be 0x093a Ox2468 , but hope this isn't rootcause.. or ? it's listed in module aliases..
