I Have Used The New Driver From The CD, But My Pen-DTU Still Doesn’t Work. Why?
Newer computers now have USB 3 ports as standard. Pen-DTUs with a serial number older than 00002800, are not compatible with these ports. Most new PC’s still have USB 2 ports available in which the Pen DTU should work. USB3 ports are coloured blue, where USB 2 ports are coloured black. If the problem persists after switching to a USB 2 port, please contact your local distributor or Detex as you may require a new Pen-DTU.
