Either:

• Download the latest package that contains the driver installer from the USRP Interfaces page.
• Or download the latest release of Zadig.exe (from the libwdi project).

USRP USB Driver Installation Instructions

1. Decide whether you want to use UHD or the Legacy interface on the USB port you just plugged your USRP into.

   UHD is the latest and greatest ("New World") interface, but from my experimentation doesn't perform as well or as quickly on Windows as it does on Linux (this is probably also due to libusb1 and WinUSB). Also, I've found it does not report hardware overruns.

   Legacy uses the old-world code in the GNU Radio source tree, which is from my experience rock solid and performs exceptionally well on Windows (with libusb0), especially at the higher data rates where UHD has had trouble keeping up (for me at least). This does report hardware overruns, but is unable to report back some of the current state of the hardware (UHD does this completely) so my USRP clients attempt to work around this.

2. Your USRP should show up in the list as device with VID FFFE and PID 0002 (unless you have a new one with the officially registered VID).

   If it does not show, go to Options->List All Devices (it already has drivers installed, but you can replace them)

3. You can edit/change the name of your device by ticking Edit Name

   If you've chosen to go with...

   1. UHD, make sure Target is WinUSB (<version>)

      Legacy, Target should be libusb0 (<version>)

4. Now simply click Install Driver, and you're done!

Here are some examples (there are many more devices/IDs than those listed here - this is just a sample):

• For ezcap, etc, use Zadig (included in installer) to set up a WinUSB end-point on the 1st sub-device of the USB composite device:

VID 0bda PID 2838 MI 00

Your VID/PID values might vary, but the MI should be 00.

• The Hama nano should be:

VID 0bda PID 2832

• For the Terratec NOXON, it appears as a single device (not composite), so just install WinUSB on that:

VID 0ccd PID 00b3 (revision 1)
VID 0ccd PID 00e0 (revision 2)

• Dexatek Technology dongle:

VID 1d19 PID 1101
