robyholmes Posted September 22, 2016 Posted September 22, 2016 Hi Promethean, One of our older Gen 2 boards stopped working the other day. We found it wasn't powering up so swapped the AC adapter on the back of the board which meant it then powered up. The board beeps on start up (As normal) and the light colour changes when the pen is close. However when we attach the USB to the laptop windows shows the 'unrecognised usb' message and no hardware is detected. We've swapped out the USB cable with a known working one and tried connecting directly to the back of the board rather than the wall plate. The laptop picks up other USB devices fine in all ports, we tried different ports with the board as well. Has the controller on the board failed? Thank You, Rob
mikeprice Posted September 22, 2016 Posted September 22, 2016 Silly question - but have you tried it on another computer? Just seems suspicious that the power and usb went together - mind you maybe the power sent a spike when it failed and lunched the controller anyway
ricki Posted September 22, 2016 Posted September 22, 2016 Try and run the firmware upgrade if that does not work after that probably the controller has gone
markiof Posted September 22, 2016 Posted September 22, 2016 Hi If the firmware upgrade does not work then I suggest contacting Promethean Technical Support direct who might be able to assist with this issue. (support.prometheanworld.com) thanks Mark

Just seems suspicious that the power and usb went together - mind you maybe the power sent a spike when it failed and lunched the controller anyway I didn't no but other USB devices worked fine in the PC and I did move ports around etc. I'll try another machine just to be sure I think. I'll try the firmware upgrade as well but I suspect it will just fail to see the board.
