I can confirm this on my system - Asus K8N-E motherboard, AMD Athelon 3000+ CPU, running Ubuntu
 "version 2.6.15-27-amd64-generic (buildd@king) (gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)) #1 SMP PREEMPT Fri Dec 8 17:50:54 UTC 2006" 64-bit.

On the Motherboard BIOS configuration, if I enable "High-speed" mode for the USB (480 Mbits/sec), The Ubuntu boot hangs, trying to load the OHCI_hcd.

My Windws XP boot on the same hardware works fine with this BIOS setting.

Changing the BIOS USB setting to "Full Speed" (12 Mbits/sec) allows Ubuntu to boot normally.

I can reproduce this fairly easily, so let me know what info you need to diagnose this.
Please provide clear and complete instructions - I'm still learning my way around Linux.
