Wireless Keyboard Questions

I checked the forum by searching but i didnt get a clear answer.

Can I use a Logitech Wireless Keyboard and mouse? Such as the wireless desktop mk300 with aTV after flashing?
I have it connected to a belkin hub and it doesnt seem to be working. Can anyone help?

Thanks

Is the USB hub plugged into the wall for power? The Apple TV USB port might not be able to power multiple devices off a non-powered hub. Also have you tried pressing the reset button on the wireless receiver and the keyboard & mouse?
