lcd=ok, usb=ok, lcd+usb = not ok

Hi!

I've got a problem while trying to use a lcd and a usb keyboard at the same time. Lcd works when the usb shield controls are not in use (no init or anything) but when I init/start using usb shield in my code the lcd starts to give some weird letters. And in the beginning when the usb shield hast done the init lcd prints "f".

There's something which interacts with my lcd in the usb host shield lib...

It looks like there is something wrong with line 15 of your sketch.

Hmm, I think it could just as well be in line 17! :o

usb host shield uses pins d9 and d10, any conflicts with your lcd??

I solved this by changing pins 11 and 12 to 6 and 7. 11 and 12 are in usb host shields usage. Thanks for your help guys!
