Hello,
I previously had the B200mini functioning on a Dell laptop I maintain,
however that is no longer the case. I now get the error message below
when using find devices or trying to probe it.
No UHD Devices Found

I have seen this exact error on multiple laptops with 2 different
B200mini's and usb cords. If I plug the B200mini into my desktop
machine, I am able discover and probe the device.
I have done all the udev rules as stated in the notes on each laptop
and desktop machine.
The machines(laptops and desktop) are all running Ubuntu, and the same
docker container with GNURADIO and UHD installed.
uhd_config_info --enabled-components
Enabled components: LibUHD, LibUHD - C API, LibUHD - Python API,
Examples, Utils, Tests, USB, B100, B200, USRP1, USRP2, X300, N230,
MPMD, N300, N320, E320, OctoClock
I am at a loss as to why this is happening....any help would be
appreciated.
Thanks,
Mark
That sounds like the firmware/fpga image is corrupt -- try re-running
"uhd_images_downloader".
