Re: lime sdr support (gr-limesdr) PyBOMBS bombs with USB access

[aardric]

Problem solved although not quite understood. I had an incorrect device 
setting in the audio sink block and leaving the entry blank (default) 
solved the problem. The libusb warning was a red herring and I haven't 
been able to find out where it came from.  So, limeSDR with PyBOMBS 
works (and on opensuse leap 15.1).
