Multiple iPods Connected to iTunes

I’ve tried, unsuccessfully, in the past to mount more than one iPod via iTunes and it’s never worked. For some reason, this morning I am able to.

I’m running iTunes on Windows XP SP2. All three iPods are connected via USB2. The 20Gb 4th Generation iPod and 80Gb 5.5 Generation iPod video both have disk use enabled and I manually manage music on both units.

Is anyone else able to duplicate this?

UPDATE: According to Apple, this shouldn’t be done.
