New Revision: 214843
URL: http://svn.freebsd.org/changeset/base/214843

Log:
  Implement ucom_set_pnpinfo_usb() providing ttyname and port number
  information through devd. My E220 now produces the notification (1 line):
  
  	+u3g0 at bus=1 hubaddr=1 port=0 devaddr=2 interface=0 \
  	vendor=0x12d1 product=0x1003 devclass=0x00 devsubclass=0x00 \
  	sernum="" release=0x0000 intclass=0xff intsubclass=0xff \
  	ttyname=U0 ttyports=2 on uhub0
  
  Note: serial/ufoma and net/uhso still provide port number and tty name
  (uhso only) information through sysctls, which should now be removed.
