I have recently gotten my raspberry pi and I have plugged in my wireless keyboard but am having difficulties typing. Just trying to log in, I get piiiiiiiiiiiiiiiiiiiiiiii when I just type pi. So I read about this and it said it was because keyboard is taking too much power so I purchased a usb hub with a external power source but I still have the same problem. Does anyone know how to fix it? is there some option that I have to enable to stop this? Also if it helps somehow I use the microsoft wireless 800 desktop keyboard
With both your keyboard AND wifi dongle functioning improperly, I can come to only three conclusions:
The set you got your Pi in (which, if you're from the UK, is from Maplin I presume) is defective with your keyboard and wifi dongle broken already.
The USB hub that came with it is broken and will not work properly.
Your Pi's USB ports are damaged in some way.
