USB Keyboard issues

My USB keyboard is pressing two keys at the same time when I press “;” and “Shift”.
For example:
When I press “;” he presses the “-” together, getting ; -.
When i press Shift, he press the Left Arrow together… Getting Shift + :arrow_left: .

Manjaro Linux on a notebook

The notebook keyboard is normal … The problem only occurs with the USB keyboard

Sounds like a hardware issue with that keyboard.
Did you try it on another computer or another operating system or when booted from live usb?

You might be able to find the manufacturer in the keyboard settings while it is plugged in. Worth a try.
