It seems that LibUSB still causes some crashes in Vista-32 when the system hibernates or powers down. It does seem that with enough jumping through hoops it can be successfully installed.
 
There's no planned Vista-64 version of libusb. Vista-64 was slow getting out of the gate, but now accounts for 20% of the hits from Vista computers at Microsoft's web site.
 
Soon, it will be time to decide how HPSDR supports 64 bits. The options I see are:
    - WinUSB
    - Cypress (who will have a 64 bit CyUSB driver in 1 month)
    - FTDI
    - Hope someone in HPSDR-land or Libusb-land can compile a 64 bit libusb and get it WHQL-certified. (Costs money, $400 I believe)
 
Yes, all the answers are a pain as the first three would require an API change with significant code re-writing and the fourth requires more time, expertise, Microsoft certification and money.
