[hpsdr] Much success on winusb in KISS

[James Brown]

That's great George.  I'm looking forward to getting your SVN output for my 
system.

Did you (or anyone else) look at LibUsbDotNet from SourceForge?  Its says it's 
a package that can be used for either libusb-win32 OR WinUsb without 
changing your source code.  I would like to try it but if anyone else has 
experience with it I would like their input.

Regards......... Jim
