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

[Eric Sander <eric.sander@gmx.de>]

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
