USB 2.0 device in USB 1.1 controller

[Jason Cortezzo <jasoncc@xxxxxxxxxxx>]

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...

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,
