Re: [Discuss-gnuradio] B205 mini on Windows 10? USB Driver not found

[Tom McDermott]

Thank you !    That solved the problem.

Steps needed:

1. Plug the B205 into the computer (the step that decides installs the driver

uses that the figure out which specific USB driver to select).

2. Run the device manager as administrator

3. Updae the driver, and search... browse...

4. For me it was located at:

C:\Program Files\GNURadio-3.7\share\uhd\images\winusb_driver\

and the set of USB drivers was there.  The Windows installer emunerated the B205mini

then figured out which driver to choose from the set and installed.

5. After done unplug the B205, then plug it back in, to enumerate USRP.

UHD drivers are installed with the GnuRadio windows installer.  However, the system may not have located them automatically and so it's installed a different driver instead that it thinks is compatible.

There are couple UHD utilities in the installation as well... I think they are under Gnuradio-3.7/share/UHD perhaps?  (Not near my PC).  I would start with those and confirm if the issue is with the UHD drivers themselves, or the GnuRadio side.

In there are a couple UHD driver files, and you can go to Control Panel, Update Driver, and Manual Choose, then navigate to that directory and pick the *.inf file that is closest.   I suspect this is the issue.

Once it's correct the UHD probe utility should find the device, and it should show up in Device manager as an "Ettus USRP B205mini" or similar.

Then hopefully GRC will pick that up and work as well.

I have installed the latest Windows version of Gnuradio from the MSI installer on the gnuradio website.

It has UHD source and sink blocks. Gnuradio Companion seems to work fine except for UHD device detection.

Have plugged a B205mini into USB3 connector on the computer. The B205 lights up and 

Device Manager indicates that   Westbridge   is present.  The first time plugging it in, Windows

went through the new device detected process and claimed it installed the driver.

However Windows device manager indicates that there is no driver for Westbridge, thus when I try to

run the flowgraph from GRC (with "" for device specifier in the UHD source block which the documentation

indicates will search for first found device if the default empty string is used).

Flowgraph indicates that no UHD device is found.

Trying to do a Windows Device manager driver update for Westbridge says that there is no

driver to be found, even when searching.

Any suggestions as to where to find the Windows 10 USB drivers for B205mini?
