Thats your onboard serial ports (uart0 and uart1).

Did you load the driver (kldload u3g) ?
what is the output of
usbconfig

it should show something like

# usbconfig
ugen0.1: <OHCI root HUB AMD> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) 
pwr=SAVE
ugen1.1: <EHCI root HUB AMD> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) 
pwr=SAVE
ugen1.2: <product 0xf103 vendor 0x2001> at usbus1, cfg=0 md=HOST 
spd=HIGH (480Mbps) pwr=SAVE
ugen1.3: <USB Modem U.S.Robotics> at usbus1, cfg=0 md=HOST spd=HIGH 
(480Mbps) pwr=ON
ugen0.2: <Back-UPS ES 650 FW825.B1.D USB FWB1 APC> at usbus0, cfg=0 
md=HOST spd=LOW (1.5Mbps) pwr=ON
ugen1.4: <ZTE CDMA Technologies MSM ZTE, Incorporated> at usbus1, cfg=0 
md=HOST spd=HIGH (480Mbps) pwr=ON


note the #s for the device. On mine, it shows 1.4. So do the matching 
command for yours so it provides the following output

  usbconfig -d 1.4 dump_device_desc
ugen1.4: <ZTE CDMA Technologies MSM ZTE, Incorporated> at usbus1, cfg=0 
md=HOST spd=HIGH (480Mbps) pwr=ON

   bLength = 0x0012
   bDescriptorType = 0x0001
   bcdUSB = 0x0200
   bDeviceClass = 0x0000
   bDeviceSubClass = 0x0000
   bDeviceProtocol = 0x0000
   bMaxPacketSize0 = 0x0040
   idVendor = 0x19d2
   idProduct = 0x0031
   bcdDevice = 0x0000
   iManufacturer = 0x0002  <ZTE, Incorporated>
   iProduct = 0x0001  <ZTE CDMA Technologies MSM>
   iSerialNumber = 0x0003  <1234567890ABCDEF>
   bNumConfigurations = 0x0001


Then provide the output of

# sysctl -a dev.u3g
