USB-DUX
USB-DUX is now open source/hardware. After 15 years, USB-DUX data acquisition boards are no longer being manufactured.
Below are the design files which you can send to a prototyping service or manufacturer. We recommend European Circuits (https://european-circuits.co.uk/) here in Glasgow / Scotland.
The Original USB based DAQ for Linux
The USB DUX is the perfect data acquisition unit for real-time monitoring and control. The board takes advantage of the real time speed and power of the USB port and is designed to work perfectly under Linux. This means that it is easy to program and works well on embedded systems or desk top computers. The board is plug and play with most distributions such as UBUNTU.
Drivers
No need to install any drivers as they are part of the Linux distributions.
USB-DUX uses the comedi framework (http://www.comedi.org). Use the packages provided by your distro. Do not compile comedi from source.
Debian/Ubuntu packages:
apt install libcomedi-dev
apt install libcomedi0
Check that you are in the group iocard. Open the groups file:
sudo nano /etc/group
and see if your username is added to the group iocard:
iocard:x:125:my_user_name
