Hi Marty,

thanks for your help.

The card is actually broken, altough it is brandnew! I tried another one
and had no problem getting manufacturer and device id and i was also
able to program it.

I do not believe there were any resource conflicts with the first card
because i was able to read and erase it. Only programming did not work.
Also, /proc/pci showed the card with correct addr/irq and device id.

Thank you!
