Hi!

I had the exact same issue on my A1200 (Mouse buttons worked, but no analog paddle status at all) and took it completely apart without finding any issues, including measuring voltages and what-not.

What fixed it for me was to plug in a Joystick to the mouseport (with machine running), move it around wildly, unplug the Joystick and plug in the mouse again.

And it works again. Give it a shot, might just work as it did for me.

Additional note:
When i measured the voltages back then they also did not be anything near the specifications i found, including one pin that was 'dead' even tho it should have had voltage on it. Unfortunately i did not keep the notes from the test, which i will definitly do the next time this happens. Basically from what i've learned that documentation is possibly outdated or not valid for all motherboard revisions. Then again i only had one A1200 to test with and i'am overall not much of a hardware chief :)

Just saying to possibly not trust those voltages that you are supposed to measure, they also were different for me. If i remember correctly, i wasted about an hour pondering the pin layout because that one pin would simply not give any voltage when the documentation said it should...

Oh, and btw, if you plug in the Joystick (tho iam pretty sure you know that) to the mouse port, and move it around, the cursor should go "wiggly" if there is any signal coming through...
