I thought suspend never worked anyway.

There never was an ID change.  The device has _always_ reported the same 
ID regardless.

With the old devices it is possible to detect the need for an FX firmware 
download by noticing a difference with the USB configurations reported by 
the device.  With the new devices there is no longer any difference.  So 
now the driver tests the device by probing it with a command that only 
works if the firmware has already been downloaded.  If the probe fails, 
the driver sends the firmware and resets the device.

(With all that said, the new devices still aren't working correctly.  I'm 
trying to solve some kind of wierd initialization race going on with the 
cx25840 in the new hardware.)
