[Linux-parport] PCI-Card VScom 210L not detected

[Erwin Volz]

Hello

I have now found the source of my problems, so I will close this tread.

Concerning the VScom 210L-Card, the problem was not parport_serial. The 
problem was connected with the setserial-script, which tried to autodetect 
all serial ports. 
This autodetecting somehow colliedid with parport_serial. It also detected 
only one of the two ports of the card, but that never bothered me much.
In the meantime I have changed the setserial-script to manual detection, and 
now everything works perfect.

It took some time to find the root of the problem, but I lerned to build my 
own kernel and several other things, so it was worth the trouble ;-)
