Keyboard & Mouse

Now I’ve got my keyboard and mouse for the Raspberry Pi RiscOS, I have found that for some reason pressing a key sometimes produces extra keys even when not pressed. I have also found that the connection to the mouse drops out every so often, which can be fixed by unplugging and then putting the mouse back in (USB connection).

AIUI a known problem!
The Pi USB Stack is based on the Linux one and Linux Pi users report the same problem. The Foundation have contracted someone to work on this.

Ah right!

Are you using a powered USB hub? AIUI this sort of thing can be caused by an insufficient power supply.

Its the power supply that you can buy with the Pi – I presume its 5 volts/watts
