"usb_relay" - USB driver for JS284 relay from

usb_relay is a driver for: http://www.j-works.com/jsb283.php It gives you an ability to connect the JS284 to the USB port and use usb_relay to turn the relay on and off from the UNIX-based system. I have used it both with Ubuntu GNU/Linux and FreeBSD.

How to build

To build usb_relay you must have libusb header files. On Ubuntu you can install them with a following command:

sudo apt-get install libusb-dev

To build usb_relay:

make

How to use

Usage of usb_relay is pretty simple:

./usb_relay on

To turn it on. To turn the relay off, you do:

./usb_relay off

You can also flash the LED:

./usb_relay flash

In case you have to debug something on your system, the -d flag can be passed to the program to get some debugging output.
