I was having a similar problem with my new ipod... it would stall here:
umass0: Apple iPod, rev 2.00/0.01, addr 2

After two hours of frustration (pissed off) I decided to repeatedly
unplugged and re-plug the device cable in... To my surprise it started

umass0: Apple iPod, rev 2.00/0.01, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Apple iPod 1.62> Removable Direct Access SCSI-0 device
da0: 40.000MB/s transfers

The trick is to rapidly (without being careless) unplug / replug the
device in 2 or 3 times... My mainboard is an Intel 845GBV with ICH4,
USB settings in BIOS are set to defaults.
