which I upped it to sometime early this year.

Neither the HRF-O nor the Nano2+, in any USB port, in any application, work.

where to look next. I actually was at that point approximately the moment I
discovered that the devices weren't being recognized by the software, but I
do TRY to clean up my own messes, Read That Fine (if often
incomprehensible) Manual, recheck my work, try to remember what mistakes I
might have made, cross-check with other hardware and software, "Ask Dr.
Google" etc, but I think I've got those bases well-covered five times over
and I'm at wit's (and patience's) end I I just want the friggin' thing to
work so I can get back to my radio hobby. I got tired of my computer hobby
when this problem beat me.

Hi Chris,

This certainly sounds like a USB driver issue on the Windows 7 system as
it's affecting multiple pieces of hardware and both work on Linux.

Going through the things that you've already tried:
 - have you removed and reinstalled the Zadig driver?
 - was there a recent Windows update that could have caused this?
 - is it just those two USB devices?

Thanks,
  Dominic
