Hi,
         I added the defs for my Sierra 875, but the box panics up 
when I connect to the port

# usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), 
AMD(0x0000), rev 1.00
  port 1 addr 2: full speed, power 500 mA, config 1, Mini 
Card(0x6812), Sierra Wireless, Incorporated(0x1199), rev 0.01

ugensa0: <Sierra Wireless, Incorporated Mini Card, class 0/0, rev 
1.10/0.01, addr 2> on uhub0
ugensa0: unexpected endpoint
