I just upgraded my system from Linux Mint 21.1 to 21.2. My system is an Intel i7-6700
based desktop with 32 GB of RAM. After loading the OS and going through my usual routine
of loading programs and drivers, I discovered that I cannot use my USRP B200mini. I tried
running a basic Gnu Radio flowgraph of USRP source to a frequency sink as a quick test.
Right after I started it, it stopped with the statement, "Done (return
code-11)". I'm not certain if this is a Gnu Radio problem, Mint problem, or USRP
problem. I *suspect* it's a Mint / USRP problem. I've loaded libuhd4.1.0 as well as
libuhd-dev and uhd-host. Normally, that's all that is required.
When I run "uhd_find_devices", I get:

Further, when I run uhd_usrp_probe, I get the following:

This does not seem correct. For example, when running the same command on
another system still running 21.1, I get much more detailed information about
the B200mini. (It also says that it is loading a firmware image right after
starting the command, which does not happen here.)
If anyone has any ideas, I'm all ears.
Thanks,
Gary
