It looks your product ID is already in urtw(4) match lists so I think
the following commands could help you.

	# cd sys/modules/usb/urtw
	# make
	# kldload ./if_urtw.ko

then plug-ins your device.  However what you should know is that
the status of supporting 8187B chipset is in the experimental and 8187B
Rev B and D doesn't tested.  In addition it looks there are problems on
8187B Rev E.  usbdevs(8) isn't no more supported in CURRENT so please
use usbconfig(8) instead of it.

Please let me know if you encounter problems to work with it.
