USB 2.0 device in USB 1.1 controller

I'm having a problem connecting a Creative Labs MuVo TX 256MB USB 2.0 storage device into a motherboard that only supports USB 1.1. I had this problem in FC2 and now also in FC3. The device works with FC2 in another system which supports USB 2.0. It also works in the USB 1.1 system when booted into a non-linux proprietary OS.

Here is the contents of syslog and /proc/bus/usb/devices when inserting and removing in both systems...

Problem System

Motherboard: Asus A7N266-VM - USB 1.1

Syslog after Removal:

I think the most noticeable difference is the "I:" line in /proc/bus/usb/devices - In the good system the driver is listed as "usb-storage". In the bad system it is listed as "(none)".

Any advice on how I should proceed?

Thanks,
