Just thought I would throw it out there.
At work I like to listen to music. The times I forget to charge my ipod it dies and I am a sad panda.... well today was another one of those days but ALAS I brought a USB cord with me... hooray... or not.
Plugging in the cord to the computer results in the computer thinking it is a hard drive... eject the hard drive and it stops charging... arg.... plug it back in and stop device... it stops charging... arg!
I debated buying a power adapter charger for the dinosaur but I would much rather put the $30-$50 toward a new ipod.
A Google search yields the exact things I have been trying... ARG! Finally out of frustration a brief flicker of the idea lamp I mask off the 2 inner pins (data pins) of the USB connector with scotch tape. Bingo charging while listening to music.
Found it to be a reversible extremely cheap solution to a problem. Although this has nothing to do with anything this board is about... it goes to show that sometimes being smart doesn't mean get out your wallet.
Just thought I would share.
