Re: If the board were missdetected... more information

Hello
First I looked it has a broken eeprom - but it cannot be as USB ID is shown correctly so it must be a driver bug. Are you sure it is stock 3.7.10 Kernel, not some media build top of that?

For some reason em28xx driver skips USB ID based detection and fall-backs to I2C bus / eeprom fingerprint detection that naturally fails.

regards
Antti

Re: If the board were missdetected... more information

Hi Antti,
thank you for quick response.
My system is a fresch Opensuse 12.3 with actual updates. I fixed the problem by giving the deviceID=86 in the modules.conf. so for me the Problem is fixed.

regards
Eric
