There is no Comedi driver for that board or any other Measurement Computing USB devices, so you'll have to find someone to write said driver if you want to use it with comedi. This is assuming you can extract the necessary programming details for the device from Measurement Computing's technical department, or failing that, can reverse engineer the information by sniffing the USB bus on Windows. There are a few USB device drivers in Comedi that may be studying. The book "Linux Device Drivers" third edition, published by O'Reilly also has information on writing USB drivers (it can be found online, but is more convenient in paper form!). For prototyping and experimentation before writing the real driver, it may be worth experimenting with the device in user-space via libusb. -- -=( Ian Abbott _at_ MEV Ltd.
