One or more of my USB devices...
I've been struggling for the past week with neither my iPod Shuffle or 5th Gen iPod video showing up in the finder or iTunes on my new Mac Pro. Needless to say, its been MADDENING!
I got it to synch once, but not since then. I've gone thru the "5 Rs", swapped dock cables, tried all USB ports, Downgraded from 10.5.7 to 10.5.4, then 10.5.5, then 10.5.6, all with the same result - no iPod recognition.
Both iPods would recognize on my old dual G4, no problem...
Then this morning, I pulled out my old 2nd gen iPod and plugged it in to charge it for a few minutes. Once it had enough juice to run on its own, I plugged it into the FW port and it was recognized immediately.
OK, so that meant there was something going on in the USB side of things. So, I unplugged everything but my keyboard and mouse from my USB ports, plugged the iPod shuffle into another port, and IT WAS RECOGNIZED! It just finished synching...
So, my next step will be to add one thing at a time back to the USB side until I have a problem again. Its gotta to be something drawing too much power or something off the USB ports.
I'll post again once I figure it out. I may have to do a little creative reconfiguring with my powered hubs to help take the burden off the computer...
