There are some devices with a knob available that reading that
register is currently
not implemented in the newer driver, netBSD people figured out that
interrupts are delivered
when a key gets pressed (even on the remote control). This is a
construction side at the moment
and it should be changed to something appropriate like the netBSD
people implemented.

There's one limitation I cut out the drx3975d (might re-add it within
the next week
to the git repository)
I know this one is required for the Pinnacle 330e and an Hauppauge based device.

If you have problems with your device please start a thread on the em28xx ML:
