[Elecraft] SVGA Keyboard compatibility

[GLEN BROWN]

Just installed the new SVGA firmware and it's great!
The only problem I have so far is that it doesn't work with my Microsoft
wireless keyboard, which uses a little USB wireless device on the computer
(P3) side.
This keyboard still works FB with the computer, but is dead to the P3.  The
P3 is ok with a wired USB keyboard.
Has anybody else seen this problem?
