Good advice! 
Here is a part of it:
configure:13177: gcc -o conftest -I/usr/local/include -I/usr/local/include -L/usr/local/lib  conftest.c -lusb  >&5
/var/tmp//cctcQ0kE.o(.text+0xa): In function `main':
: undefined reference to `usb_get_driver_np'
...
configure:13204: result: no
configure:13209: error: Can't find libusb. On ubuntu, try sudo apt-get install libusb-dev

According to [1], this function is implemted on Linux only - a Linuxism.
I'll see if I want to fix it.
