[hpsdr] Win7-64 usage

[Berndt Josef Wulf]

 G'day Steve,
 
You need a copy of the libusb0.dll, which doesn't come with PowerSDR 1.9.3, 
but a signed version can be downloaded from the OpenHPSDR and copied into the  
the PowerSDR directory. You would expect CPU load to go up when running 
software in on a virtual machine.
