may I commit this small umodem patch ?

There was a discussion back in september about adding
support for basic CDC tty devices in umodem.c.
This lets you talk to a number of usb devices built around
microcontrollers (e.g. Atmel), and puts us on par with
Linux and Windows in terms of supporting these devices.

Because this simply requires the small patch below to the
probe/attach routine, so if there are no objections I plan to add
this to the system (CURRENT then RELENG_7 and RELENG_6) in the next
few days.
