problems with cdce and/or usb?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

It had been a while and a number of source updates since I last plugged
my OpenMoko Neo Freerunner into a USB port for anything other than
charging.

The cdce? interface used to work fine, but I tried again today and got
the following logged in /var/log/messages:

The output of 'ifconfig -a' shows only "cdce1" (which is why I had
'ifwatchd' monitoring cdce1).  When unplugging the cable, I get:

[...]

[...]

The machine in question is:

NetBSD shadow.bozonet.ntc 5.99.55 NetBSD 5.99.55 (SHADOW) #1: Tue Aug 16 
12:51:11 CDT 2011  
sysop%shadow.bozonet.ntc@localhost:/d0/nbsd/current/obj/i386/sys/arch/i386/compile/SHADOW
 i386

built from sources updated just minutes before the timestamp in
the output of 'uname -a'.

In the past, it would attach at cdce0, my ifwatchd script would
configure it, and I could use it just fine.  I'm not sure when
things broke.  I first noticed the problem with sources from 3
August on the same machine.

I need to double-check operation on netbsd-5.

Thanks.
