Hi, I try to install the driver for my advantech PCI1753 io card on Ubuntu
10.04. My config:
processor: Intel core 2 duo  E7400 2.8GHz
Ram: 2GB
Hard disk: 2x500GB in Raid 1

I follow this topic:

The problem start when I try to load the rtai_smi module
sudo /sbin/insmod /usr/realtime/modules/rtai_smi.ko
I have this error:
insmod: error inserting '/usr/realtime/modules/rtai_smi.ko': -1 No
such device

I try to continue the topic, but when it's time to configure the card:
sudo comedi_config -v /dev/comedi0 pci1753 2,0xf
I have this error:
configuring driver=pci1753
Configure failed!: Device or resource busy
Check kernel log for more information
Possible reasons for failure:
  Already configured

I Check the dmesg and I found this:
[    9.933758] adv_pci_dio 0000:02:0f.0: PCI INT A -> GSI 19 (level,
low) -> IRQ 19
[    9.933767] , b:s:f=2:15:0, io=0xd800.
[    9.933771] 8255 support not configured -- disabling subdevice

[    9.933778] 8255 support not configured -- disabling subdevice
[    9.938959]   alloc irq_desc for 26 on node -1

does some one can help me.

thanks in advance,
