Unfortuantely you didn't specify how you installed simtrace2, i.e. where those
pacakges listed below originate from:

maybe you have a mixture of distribution-built packages (libosmocroe?) and
osmocom-latest (simtrace2?)

This is a function implemented in libosmocore commit

i.e. any version of libosmocore >= 1.3.0. The usb support is built automatically
unless somebody compiles libosmocore with "./configure --disable-libusb"
So in any case, IMHO, this kind of error can only occur if:
a) your simtrace2 software was built against a libosmocore with libusb support
b) your runtime system has a libosmocore _without_ libusb installed
Regards,
Harald
