My favorite bug this month was while setting up a development environment with the AVR-ICE.
I tried to save some company money by not buying the (optional) case and programming cable assembly -- figured I could just use another not-80$ SWD cable (also 3d-printed a case and a SOT-23-6 programming adapter).
After much cursing and hair pulling, I noticed that the header for the SWD cable was installed upside-down on the PCB. So the red wire on the ribbon cable was pin 10 instead of pin 1. In their defense, they did correctly indicate this on the solder mask, I just didn't see it through the (opaque) case.
My best guess as to why the cable assembly costs 80$ is that they again reverse the pin order on it to silently fix the bug on the PCB instead of just shipping a standard cable.
It turned out to be worth the engineering time to deal with the bug, but not by as much as I hoped. It's a pretty neat product despite this bug, definitely more modern than the venerable STK500 that I used previously (which itself had been converted to a USB device after the level converter failed).
