Keyboard behaves unexpectedly while POE2 is running

Recently, I've started having spurious WASD movement key inputs in-game and in town. The issue starts randomly after playing for a while and persists once it manifests, surviving restarts and PC reboots. It varies between constant repeated inputs in one direction blocking the other three (running me to one end of the area) and sometimes one or two directions working and the others not working. Because it's constant, gameplay is basically impossible. It seems kind of like how I'd expect stuck key polling or input buffer overflow problems to appear. I verified in Notepad (via alt-Tab) that these key inputs aren't stuck or repeating. Windows keyboard repeat settings are at default. But on returning to the game the behavior persists.

I'm level 40 in Act III and running the new patch released two days ago. I never had any previous keyboard issues before the last two days. No recent system software or hardware changes that would cause it to start now. I'm using WASD + Mouse on auto and tried changing related POE2 input settings to no effect. Win10 x64 on AMD.

I might have found a solution for this issue. Try connecting your keyboard and mouse to a USB 3.0 port instead of a USB 2.0 port. This problem is likely caused by the high polling rate of gaming keyboards, and it seems that PoE2 isn't fully optimized to handle it on slower USB connections.

This fixed my issue. Many thanks

SAme issue here, worked fine until a couple of weeks ago.
Now starts of fine then after playign for a period, the movement begins being eratic, moving me off in different directions. Generally getting me killed of course.
Im in Act 2 on Cruel currently.
