Hi,
I'm having issues with my keyboard - as though key presses are missed or keys are held down.
I know the common cause of this is power issues however in this case I think it is something else.
This ONLY happens under the latest build of Raspbian - other OS are not affected (eg RiscOS, Arch etc) and the problem goes away until reboot if I unplug the keyboard then plug it in again. It is unaffected by overclock settings etc.
I am using a 2A USB charger for power and the keyboard is plugged into a powered USB hub. There are no other peripherals plugged in.
Any ideas?
Cheers
Rab

You don't say what brand/flavour of keyboard. It could be important. 
Noob is not derogatory the noob is just the lower end of the noob--geek spectrum being a noob is just your first step towards being an uber-geek
