Atmel ICE
This device is used to program various Atmel designed processors.
It has one serious fault, in that the sockets are wired back to front but otherwise it works well. The dumb wiring is the main reason for this page. I got it working fine once and now forget how it's broken so need to rediscover the stupidity yet again.
I got the PCBA version of this device in 2019 for £47, they now cost £90 in 2022. Microchip outpace inflation like nobody else.

Ports
The key in the port is on the wrong side so you can either plug the cable in back to front (not recommend) or cut the notch off your cable and turn it around and plug it the right way around at the other end (recommended but I don't accept liability for any error). Maybe Atmel (now MCHP) should just employ competent engineers.
PS. MCHP will sell you mis-wired cables so you do not need to do the above, but having mis-wired cables in your collection may be even worse.

Both sockets contain the same signals just wired to
different pins.
