On our newer devices (U3/U6/UE9/T7), the digital inputs are pulled high (3.3V) internally. So to create counts you would tap a wire connected to GND. But on the U12, the digital inputs are pulled low internally, so to create counts you would tap a wire connected to +5V.What do you mean with "the digital I/O is normally low on the U12, so you would use a jumper from +5V to create test counts"?
If you want to send it back to us directly, we can take a look at it. Contact [email protected] to follow-up on that.What else can I try? Send it back to the store I bought it? But I donīt have warranty any more...

The counter problem here was that the watchdog was stuck on. See the new item #6 on the U12 Hardware Troubleshooting page:
