iPod Kernel Panics?

Occasionally, when I unplug my iPod Nano (It's an oldie, it's one of the first nanos) my iMac G4 with Tiger on it will panic on me. I can't read the logs. This time, it panicked after I put it in sleep mode in 90 degree weather, but I don't know if that is affecting it at all. Here's the log:

I can tell it was the USB, but I don't know WHY it panics. Can anyone interpret it for me?


Thanks. 🙂
