I am also having problems connecting my two iPod shuffles to my G4 Powerbook (Titanium, 667 MHz). Got the iPs three days ago, both worked fine the first time I connected them. I loaded them with music and charged 'em up. A day later I reconnected one of them and again it worked fine. BUT the next day, I upgraded from OS 10.3.8 to 10.3.9, now neither iPod shuffle is recognized by the Powerbook. I plug it in, and I get a green light for about a second. Then it goes out, a second later it flashes green for a split second, then starts blinking orange constantly. The computer does not recognize that anything has been plugged in. iPs works fine when not connected to the computer.
I find it curious that Apple is telling people to send back their iPs when they encounter this problem. Since both of my iPs stopped being recognized by the Powerbook at the same time, after a software upgrade, I seriously doubt the problem is a defective iPs. Sounds like a software/firmware error to me.
Reinstalling iTunes & iPod Updater did not help me.
Any help?
