Did anyone had this kind of problem?

I installed a driver gigaset 108.

Tryed to sets of drivers:
Original drivers: 1.0.15 - Has 2 files athfmwdl.inf net5523.inf (net5523 reports driver installed) but not present. Tryed the -d switch. But it doesnt load.

Tryed other driver.
has only net5523.inf (this one works, i see that the device is up but my computer freezes).

I am using Ubuntu 6.10 - Original 2.6.17.x kernel and i compled my own 2.6.20.2

I tryed lots of this to get it work. The problem is also when it FREEZES i searched to logs for some more info. But it
doesnt go that far. So I really dont know whats wrong.
