Was able to reproduce the issue on Slackware x64 with get_version. If you use strace, you should find that you're still attempting to pick a library from /usr/lib64 or something, rather than the new one in /lib64.
Basically, this is what I did (after uninstalling libusb-1.0 from package manager, which I guess did not remove all the 64 bit binaries). ./configure --libdir=/lib64 --prefix=/usr --disable-static make make install cd examples gcc -I /usr/include/libusb-1.0/ -lusb-1.0 -o xusb xusb.c ./xusb -x -> undefined symbol: libusb_get_version strace ./xusb -x -> found that /usr/lib64/libusb-1.0.so.0 was being called -> looked into /usr/lib64 and found the libusb libraries there were dated back to 2010 rm /usr/lib64/libusb-1.0.so.0* ./xusb -x -> works I also tried xusb with -i option, that calls on libusb_get_port_path() and it works fine, so I'm pretty sure that libusb_get_port() should work too if you remove all existing traces of old libusb libraries. I guess the old libusb you have is 1.0.9 (with get_version) whereas the one I had was apparently 1.0.6, which explains why mine would fail on get_version (introduced in 1.0.9 for both libusb and libusbx) and yours on get_port (introduced in post 1.0.9 x only).
