Program and library to control the USB-SD-Mux device
The program has the same interface as the original python control program by the manufacturer:
$ usbsdmux /dev/sg0 host
$ usbsdmux /dev/sg0 dut
$ usbsdmux /dev/sg0 off
If you want to run the program as normal user you can set the setuid flag:
$ sudo chown root /path/to/usbsdmux
$ sudo chmod u+s /path/to/usbsdmux
