Pullup is a 1K measuring 0.995k, I have added another resistor in series each but it doesn't make any difference 🤔
5576 Plate Spring by Ricoh, not exactly sure which 002 or 001
I've been testing on a normal keyboard.
There is no HID-Listen output at all, it's not even finding the device 0.0
Apologies if this is a stupid suggestion, but did you use the same software to flash the PS/2 firmware as you did the ADB? I only ask because I recently assembled a Soarer converter, and while QMK Toolbox claimed the flash was done without errors, it turned out it wasn't flashing at all, and while I was seeing the HID profile built into the default Pro Micro firmware, HID listen didn't see anything. Nothing worked of course. I had to download avrdude separately and flash with that.
I can't recall what I used to flash the ADB version. Maybe Arduino IDE, because I used to flash Soarer's with Arduino IDE (I forgot how, it's been years
