$ ldd bcmxcp_usb
     /usr/lib/arm-linux-gnueabihf/libcofi_rpi.so (0x401b4000)
     libusb-0.1.so.4 => /lib/arm-linux-gnueabihf/libusb-0.1.so.4 
(0x4014f000)
     libpthread.so.0 => /lib/arm-linux-gnueabihf/libpthread.so.0 
(0x40068000)
     libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0x401bd000)
     /lib/arm-linux-gnueabihf/ld-linux.so.3 => /lib/ld-linux-armhf.so.3 
(0x40037000)

So yes, looks like it's linked to libusb 0.1.

Thanks for your help!
