Problem when running "comedi_config"

Hi,

 

I have problem running the "comedi_config".

 

After running "modprobe ni_labpc_cs" successfully, I tried
"comedi_config -v /dev/comedi0 lab-pc-1200 0x200,4", but I got the error
message:

Configuring driver=lab-pc-1200
512,4,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

Configure failed: Invalid argument

Check kernel log for information

Possible reasons for failure:

 

After "dmesg" is got the mnessage:

Comedi0: ni_labpc: lab-pc-1200, io 0x200, irq 4

Unable to allocate irq 4

Comedi0: ni_labpc: detach

 

Anyone can help me here?

 

regards,

Waiyong
