I have never done anything with the pvrusb2 to try to verify operation 
after a resume.  I seriously doubt that it would work if I tried.

As for firmware, there is no firmware needed for IR support beyond the 
FX2 firmware needed to use the entire device at all.  If the pvrusb2 
driver is still able to communicate with the hardware and other bits of 
internal stuff within it, then the FX2 is healthy and thus firmware is 
not the problem.

You might try unloading the pvrusb2 driver and reloading it (i.e. 
"modprobe -r pvrusb2; modprobe pvrusb2").  That should cause everything 
to reinitialize and clean up any messes left by a suspend.
