So I got new a HP USB keyboard with my MacBook Pro. It worked fine for a couple of weeks. Now it suddenly stopped responding.
After a lot of research on the web, I already tried the following:
- Use different USB ports
- Use an extension cable
- Use connect through a different device (extra USB port on laptop fan stand)
- Restart computer
- Reset PRAM
- Reset SMC
- Safe mode
I know the keyboard is fine, because it works on a different PC laptop.
I know the USB ports work with other devices.
What could be the problem, what other steps could I try?
