I used insmod, which does the same (or so I hope :S)

Now starts the fun .
./comedi_config -v /dev/comedi0 das08 0x300
just says
configuring driver=das08 768,0,0,0,0,0 .... (lots of 0s).....,0,0,
comedi0: das08: 0x0300
This would look normal if it wasn't for the fact that the card is NOT
plugged. :(
Just have it on the table.
/proc/comedi also happily states that a das08 board (with 5 subdevices) are
in their place.

so do you have an idea of what das08 is comedi_config (and friends) talking
about?
