USRP Open Session Error

From time to time I get the error below when initiating a session with my USRP-2901.

There are no recovery from the error besides disconnecting the USB-cable and then re-connect it after a few seconds.

Is it a driver issue, Windows issue, USB issue or some problems with the hardware itself?

Any advice is helpful at this point.

I had a similar issue on a UUT with a usb port, and even turning off/on the power to the UUT did not help. So I suggested we install a relay on the usb-cable to unplug it. However, the issue was eventually resolved with a new firmware on the UUT. So my guess is driver/firmware issue.
