I am running Win7 X64 on an intel quad 4 board.
Skywalker-1 Everything works

Prof 7500 Nothing works

TBS QBox II Motor control works, Diseqc does not work,
driver cashes a bit :}
I'm sure it's just a matter of time until the drivers mature.
Neither the Prof or QBox have worked worth a crap in any other app I have tried.
I'll call this the "64 bit blues"
