just wondering if there are any issues while connecting new ipod shuffle or any new ipod through new imac's aluminum keyboard usb 2.0 port, cause i tried connecting shuffle through keyboard and it read it the first time but then tried ejecting it and had problems connecting it again while having the imac receive the ipod, i ran techtool deluxe, the program that came with applecare, and it said that usb ports were running correctly, does that apply also to keyboard usb ports? thanks
