iPod refurbished iPod Shuffle problem

i bought a refurbished 1 GB iPod Shuffle last month and about a week in it started to act funny. it wouldnt mount in iTunes sometimes and i had to re-dock it about 10 times to get it to show. now when i plug it into my MacBook Pro my kernel panics .

here is what is says in Console right before it panics.


when i plug it into the USB 1.1 port on my white Apple Pro keyboard iTunes recognises it fine and can sync but i get a message saying it will only sync at USB 1.1 speeds (understandable). ive tried different ports but it still happens (sometimes a system freeze instead of a panic, until i pull it out of the dock).

BUT when i plug in my older 4G iPod it is recognised and syncs fine in iTunes. whats the deal? is the iPod screwed or is there something wrong with my Mac? thoughts?

thanks. yes i used the same USB port when testing my other iPod. i also tried all my other USB ports with the Shuffle and thats when i found out it worked with a USB 1.1 port.

^ yeh thats what i was planning on doing but just wanted to check. its just annoying having to call Apple as its refurbished and shouldve been checked in the first place.
