Unfortuantely you didn't specify how you installed simtrace2, i.e. where those
pacakges listed below originate from:
libosmocodec0_1.4.1_amd64
libosmocodec-doc_1.4.1_all
libosmocoding0_1.4.1_amd64
libosmocoding-doc_1.4.1_all

libosmocore-dbg_1.4.1_amd64
libosmocore-dev_1.4.1_amd64
libosmocore-doc_1.4.1_all
libosmocore-utils_1.4.1_amd64

libosmogsm15_1.4.1_amd64

libosmousb0_1.4.1_amd64
libosmovty4_1.4.1_amd64
libosmovty-doc_1.4.1_all
osmocom-latest_0.0.0_amd64
simtrace2-firmware_0.5.2_all
simtrace2-utils_0.5.2_amd64
maybe you have a mixture of distribution-built packages (libosmocroe?) and
osmocom-latest (simtrace2?)
$ simtrace2-sniff
simtrace2-sniff: symbol lookup error: simtrace2-sniff: undefined symbol:
usb_open_claim_interface
This is a function implemented in libosmocore commit
commit d462e3fa7b22b046b1c3d7cb46be5760b6fd308a

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
