Have you tested to confirm that FX2 firmware download without USB
reset still leaves the DTV firmware commands operable?

In other words, I'm not entirely sure about this fix. If both Digital
and Analog still work with the patch included, then as far as I am
concerned, its fine for stable.

Greg, this is already in Linus' tree as of a few hours ago. I had
already cherry-picked it and had planned to send it off to you after
testing it myself, but I probably wont get to that until Saturday or

If Mike Isely can confirm that Digital modes still work on the HVR1950
after a firmware download without an FX2 reset, then we don't need to
wait for my own testing.

The changeset in Linus tree is: c82732a42896364296599b0f73f01c5e3fd781ae

Please wait on test results from Mike Isely or I confirming that
digital mode still works properly before queuing this one.
