yes, it is. The debian config put is as a module. I load it (I guess) with :

sudo modprobe firmware_class

no problem. 

Then I load the comedi driver:

sudo insmod comedi_kcore/comedi.ko  

no problem,

And after, the jr3 driver, but I got with dmesg: 

jr3pci: module license 'unspecified' taints kernel.
jr3pci: no version for "comedi_add_drv" found: kernel tainted.
jr3pci: Unknown symbol device_unregister
jr3pci: Unknown symbol device_register


so, I cannot load the driver. What I'm doing grong?
