Hi all.
It is the very first time I see this error. I'm using a fresh Ubuntu 20.04. Any clue?
$ simtrace2-sniff simtrace2-sniff: symbol lookup error: simtrace2-sniff: undefined symbol: usb_open_claim_interface
$ lsusb | grep Osmo Bus 002 Device 002: ID 1d50:60e3 OpenMoko, Inc. Osmocom SIMtrace 2
Find attached a $ strace simtrace2-sniff output in case it helps. Also attached the list of osmocom and simtrace libraries installed.
Dear Felix,

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_1.4.1_amd64 libosmocore16_1.4.1_amd64 libosmocore-dbg_1.4.1_amd64 libosmocore-dev_1.4.1_amd64 libosmocore-doc_1.4.1_all libosmocore-utils_1.4.1_amd64 libosmoctrl0_1.4.1_amd64 libosmoctrl-doc_1.4.1_all libosmogb11_1.4.1_amd64 libosmogb-doc_1.4.1_all libosmogsm15_1.4.1_amd64 libosmogsm-doc_1.4.1_all libosmosim2_1.4.1_amd64 libosmo-simtrace2-0_0.5.2_amd64 libosmo-simtrace2-dev_0.5.2_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?)

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

Hi Harald, you nailed it.
The packages were an old custom built with some custom parameters.
By just installing the osmocom Ubuntu 20.04 apt repository ( https://download.opensuse.org/repositories/network:/osmocom:/latest/xUbuntu_...) simtrace2 runned perfectly.
Thanks.
