I'm currently using an IBM Model M keyboard with a PS/2-to-USB active adapter. When I type fast on my main PC, almost any key will get "stuck" and keeps repeating until I press another key.

It also causes my mouse to stop functioning correctly. Here is the weird part. When I connect the keyboard to my laptop with the same adapter it works flawlessly. Why? Please help me fix this so I can keep typing on this lovely keyboard without issues.

Example: "Keyyyyyyyyyyyyyyyyyyyss".

    Mine does this once in a while. I suspect it is the USB-port very temporarily not supplying enough power. Try some other ports. Commented Feb 22, 2023 at 21:07

    No idea. Does it change if you put a (n over) powered USB hub in between? Commented Feb 22, 2023 at 21:33

    If the keyboard itself works, then the adapter is faulty. Mind mentioning which adapter you bought?

    Does this also happen with another USB keyboard and your main PC? Commented Feb 23, 2023 at 9:43

    The Model M is famously very picky about USB adaptors, I think due to being at the extreme re: voltages.
