Ok, I have download, compiled and installed. I'm using xenomai 2.4-rc4. All 
have compiled without any problem. Howeber I don't know how to use it.

If I try to install the modules:

insmod comedi.ko   

no problem

but if I do:
 insmod ./comedi_drivers/misc_drivers/jr3pci.ko  

I got

insmod: error inserting './comedi_drivers/misc_drivers/jr3pci.ko': -1 Unknown 
symbol in module


where the dmesg says:

jr3pci: no version for "comedi_add_drv" found: kernel tainted.
jr3pci: Unknown symbol release_firmware
jr3pci: Unknown symbol device_unregister
jr3pci: Unknown symbol request_firmware
jr3pci: Unknown symbol device_register
jr3pci: Unknown symbol release_firmware
jr3pci: Unknown symbol device_unregister
jr3pci: Unknown symbol request_firmware
jr3pci: Unknown symbol device_register

and now I'm blocked ....
