Try the following............
protocol=2 (That's for "EDSSl"; EuroISDN)
The default settings for this card is normally
io=0x300
irq=5
==> Check your jumper's before.
For HiSax a AVM A1 card is Type 5
or you can just try to load the driver from the command-line
with
modprobe hisax.o id=HiSax type=5 protocol=2 io=0x300 irq=5
output should be in /var/log/messages
the last line should be
...................................kernel: HiSax: module installed
if you get an error try other io / irq
you can find an free irq with
cat /proc/interrupts
hope this helps
