6.0-current and USB modem problem

[Andrew Jones]

After cvsuping to current and then building the world with a new kernel 
and everything, I found that no matter what I did, the usb modem using 
ucom0 didn't work; it would hang with trying to dial out (it would say 
'working in whatever mode' then hang). After reading commit logs and the 
updating file, I changed the device name in /etc/ppp/ppp.conf to the new 
one (cuau0) with no avail.

Anybody know why this is happening and/or how to fix it?
