Thread: PS2toUSB adapter doesn't work in certain usb port.

I'm having a weird problem here. I just finished cleaning my PC and my ps2 adapter no longer works in certain usb ports, I tested all the ports with a laser mouse, a G15 keyboard, a Xbox 360 pad and a external HD, they all worked. When I plug the adapter in the faulty usb ports there is a pop up saying the device didn't worked properly and Windows doesn't recognize it.

I don't think those are toasted because like I said I tested 'em with a bunch of devices and they worked. What can cause that?

Thanks.

Try uninstalling the USB root hubs in the device manager. Then restart. They will reinstall
When the PC restarts.
