Fix deprecated libusb_get_port_path and libftd undefined types.

The libusb deprecated fix is present from some time in the tree.

The second is by messed up inclusion headers.

PS: Do you still manage this repo? I have some mods regarding APB2RSTR and APB1RSTR
registers. I'm doing some libs and testing  Olimexino STM32 board which requires access to it.
