Yes, that's what I meant.

I don't use Linux for any serious work... just tried to provide a Linux 
version as well. And since I usually need input (receiving) it doesn't 
make any sense for me to get the Erwin Rol driver working.

Just had an idea concerning your problem: what about replacing the file 
usb-serial.h that comes with my hacked driver with the one that came 
with your linux distro? Maybe there's something in this file that 
conflicts with your kernel?

Another possibility would be to modify your original ftdi_sio driver. 
Look in the supplied ftdi_sio.c for the comment /* hack-hack by 
olaf.matthes at gmx.de */ and apply the same change to your original
