Hi,

Can you dump "kldstat" at the different times?

I guess it may be just be that the wrong module is loaded first, so it 
grabs the device, because there are no other drivers loaded, even though 
ums is a generic driver.

Try loading all relevant drivers in /boot/loader.conf . Then the attach 
order shouldn't matter.
