Modem on PB g4

[Andrea Giusto <giusto@economia.unibo.it>]

Hello guys, 

so, the problem is that my modem is 
Vendor=05ac ProdID=8203 Rev= 5.26
that (no need to say it) is not supported by linuxant. Since I am going to 
sell the old laptop now I really need a working modem...
My choices boil down to 
* bothering to death some saint man at linuxant (which I am not going to do)
* OR buying some external hardware that is currently supported. 
Now the point is: is there any external (perhaps) usb linux supported modem 
that fit my pbg4 12''?
Thanks to all
