BUFFALO USB Wifi client WLI-UC-GN and both idProduct numbers

[Daichi GOTO]

One of PC peripheral parts makers BUFFALO (a.k.a Melco) sells
USB-base Wifi client called "WLI-UC-GN" that's cheap and
reasonable to change old-PC to Wifi-able PC.

And we have its entry in sys/dev/usb/usbdevs already.

% grep WLI-UC-GN /usr/src/sys/dev/usb/usbdevs
product MELCO WLIUCGN		0x015d	WLI-UC-GN
% 

I don't know well the policy of usbdevs file entry, so
please tell me if you know something around this topics.

A FreeBSD user using WLI-UC-GN realized that it has 
another idProduct number of usbdevs. He says it has 0x014f. 
For test, he bought another "WLI-UC-GN" device and found 
that it says it has 0x015d. Fortunately I have "WLI-UC-GN", 
and my device's idProduct is 0x015d.

>From some reports, it seems that early model of "WLI-UC-GN"
has 0x014f, and after BUFFALO changed its chip and it says 
0x015d.  In this case, what should we do?  Can we insert a 
line as follow to sys/dev/usb/usbdevs or not?
