Make it compatible with older libusb, up to 1.0.12

Apparently, even some modern Linux systems (e.g. Centos 7)
still have very old libusb versions installed (e.g. 1.0.15).
To solve this, instead of libusb_get_port_numbers()
use equivalent deprecated API libusb_get_port_path()
which was introduced in libusb 1.0.12.
