From the vendor site
(which you could have mentioned) and marketoid drone speek like this
I only get "telephone (chip: Qualcomm MSM6025) type WLL (Wireless Logical Loop) (..) can be connected to PC for data communication (RS-232C or USB)"
. Couldn't find the thing in the Linux-USB Overview
database so maybe it's too new. What you should do is connect it to a GNU/Linux computer (fill in your account details please), gather all info for the device like with 'lsusb -vv' and see if the chipset returns anything in the database. If it doesn't you could try and fnd whoever does kernel USB development and see if you can support them in getting the device added.
Admittedly this all isn't much but at least it should provide a lead.
