[5.0] USB device ignored on boot

[Andreas Wrede <andreas%wrede.ca@localhost>]

I am running NetBSD/amd64 5.0_STABLE on a Gigabyte GA-MA78GM-US2H  
motherboard with three uplcom(4) USB to serial adapters.  On boot,  
only two of these are recognized, I have to manually un- and re-plug  
the third adapter in order to get it attached. (See end of the dmesg  
output). Un- and re-plugging is not even a work-around since the  
machine is running remotely - unattended.

I also noticed that the output from the attach of the second uplcom(4)  
adapter gets intermixed with other boot messages:

[...]
ucom0 at uplcom0
uplcom1 at uhub1 port 1boot device: wd0
root on wd0a dumps on wd0b

uplcom1: Prolific Technology Inc. USB-Serial Controller, rev  
1.10/3.00, addr 2
[...]

Is there a locking issue here?
