Hi Rob,

The device changing after uhd_find_devices is a good sign. Please run
uhd_usrp_probe as well to ensure the FPGA is loaded correctly.

Zadig is always launched regardless of the state of your installation, so
if you've already installed the INFs for your USRP then you should be fine
and can close it.

The package with HDSDR/ExtIO_USRP actually already contains UHD, so it's
actually not necessary to install the official binary distribution from the
Ettus package. Of course you can do this too if you like, just be aware
about potential DLL loading conflicts. If you're not having success, and
you're able, use something like the Profile feature in Dependency Walker to
check which UHD.dll is being loaded-it should be the same one that is in
HDSDR's directory.

Kind regards,
