Creative Nomad MP3 / EHCI problems

Hi,

I updated from CVS about 2 days ago and rebuilt kernel and world.

I am having problems with my Creative Nomad MP3 player and EHCI.
The Creative Nomad MP3 player is accessed via the ugen driver.

I am using the Gnomad2 ( http://gnomad2.sourceforge.net ) program to 
access the MP3 player and upload files to it.

When gnomad2 starts, it tries to scan the songs on the MP3
player, but it never completes.

I set the following syctl values:

hw.usb.ehci.debug: 1
hw.usb.ugen.debug: 1

I don't know where to look for useful information.

I got some of this output from dmesg:

Any ideas how I can further debug this problem?
Thanks.
