This is kind of cool
From the iPod docs you'd think it couldn't talk USB1.1 at all - but I have it connected to my work laptop, which is USB1.1, playing music with iTunes. (I'm not syncing it to work - not enough drive space to bother anyway). I need to finish ripping my CDs (about 2/3 of the way there now), and then I need to manually select what I want on my iPod - right now I'm letting iTunes auto-fill it. But there is stuff I'm highly unlikely to listen to.

Hmm, maybe I need the 40GB model... ;-)

USB 2.0 is backward compatible with 1.1. It'll work but it'll be really slow.

It is possible to have a device that just doesn't work with USB1.1. All the iPod docs seem to beat on that "You MUST have USB2.0!" kind of thing. It gives the impression that it will just refuse to work.

USB1.1 itself is funny - what most people think of as USB1.1 - 12Mbps - is high speed USB1.1. The base spec is 1.5Mbps.

Not as such. It'll just take some significant fraction of forever, specifically about 12-15 hours to load up a 20GB drive -- that's how long it took to load up the 20GB disk I put in my old Nomad Jukebox. You really don't want to do that.

I've also found that USB high speed doesn't hold a candle to Firewire 400. Despite having a higher absolute bandwidth the USB overhead noticeably cuts into that and USB knows nothing about bandwidth allocation. That is, any device can hog all of the available bandwidth leaving everything else sucking mud. Try putting a disk drive and a DVD burner on USB and watch as they trip over each other. Do the same on Firewire and watch them coexist without squawking.

Oh, yeah: the USB Consortium (or whatever it's called) CHANGED THE NAMES OF THE SPECIFICATIONS. There is no "USB 1.1" anymore. What you call USB 1.1 is now USB 2.0 Low Speed and USB 2.0 Full Speed, and USB 2.0 is now USB 2.0 High Speed.

And what do you mean... you don't have a 60GB iPod? :)

I got the 20GB U2 model for $250 - which was too sweet a deal to pass up.

My laptop only has a 4 wire FirwWire port, so no power to charge the iPod. Plus I haven't bought a 4to6 adapter yet. ;-)

USB1.1 at work is fast enough to playback music from the iPod, which is all I'm doing. I'm not going to try to sync with it. :-)
