Experimental Physics and
Industrial Control System

Thanks Eric! I've been thinking about building an EPICS soft IOC using
Voyage Linux on a PC Engines Alix board with Phidgets USB devices for
sensing and control. Your project looks like a good place to start
tinkering and exploring the issues before I buy any new hardware.
Thanks!

I suggested using a USB mouse with the switch wired across one of the buttons.   As a proof of principle I created a small driver to show how the libusb routines could be used with ASYN to read values from a USB mouse.
