Not sure what has happened but my interface has suddenly stopped working. The usb light on the UR24c constantly flashes and the output light cycles one for about 2 seconds and then off for approximately 4. The unit is powered but no longer detectable by windows. I have tried all the USB ports including those on a usb expansion PCI card. I have tried different leads and also tried the 5v DC micro usb too.
I have not updated any software and I can only assume the hardware has failed. I purchased it new about 5 months ago.
