[amsat-bb] Satpc32 and ICOM 9700

[Mark Hammond]

John brings up a very good point about not allowing the USB ports to 
sleep.  Another consideration---with all the various dongles, SDR, and 
such I have gone to using external powered USB ports whenever possible.  
Much less problems with those (as compared to internal ports).
