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

[aardric]

Hail,

     I installed gnuradio with limesdr support by the gr-limesdr recipe. 
All required recipes were modified to accommodate opensuse leap 15.1. 
Installation seemed to happen without a problem. gnuradio companion runs 
examples without the lime blocks; LimeSuiteGUI runs the hardware 
connected via USB 3; soapy runs the hardware connected via USB, however, 
running a gnuradio example using lime blocks with connected hardware 
results in a core dump with error:

libusb: warning [usbi_clear_event] internal signalling read failed
libusb: warning [usbi_clear_event] internal signalling read failed
error libusb_handle_events Other error
error libusb_handle_events Other error


This did not happen with a non-PyBOMBS build and install of gnuradio.  I 
am investigating but first checking to see if this is a known problem.
