Hello Dave,

Thanks for posting again. I don't know if anyone else has tried the B100
using the Windows UHD+GNU Radio binaries. Are you connected to a USB 2 only
port or to a USB 3 port? I would try a dedicated USB 2 port if possible.

Also, I don't believe that permissions issues exist to the same degree on
Windows, but can you try running uhd_find_devices in an administrator
prompt?

Regards,
Derek
