Re: test_with_parallel_port

Hi,

I had the same problem to configure the device driver,... when I did

comedi/config /dev/comedi0 comedi_parport 0x378
so I executed the command dmesg and I saw :

parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE]
parport0: irq 7 detected

I tried :

comedi/config /dev/comedi0 comedi_parport 0x778

and now it runs very well.

I think the base address 0x378 is already taken and the address 0x778 is 
another address for the same parallel port.

Sorry for my english

Good luck
