Let us to use our libusb(3) in Linuxolator.

Browse Source 
With this change, Linux binaries can work with our libusb(3) when
it's compiled against our header files on GNU/Linux system -- this
solves the problem with differences between /dev layouts.

With ported libusb(3), I am able to use my USB JTAG cable with Linux
binaries that support it.
