If you have a modem that you cannot identify, you can go to www.modem-help.freeserve.co.uk/chips.html, and enter data that will not only help you identify you modem, manufacturer, and chipset, but the database of drivers is rather extensive and will be listed for you according to operating system. If your modem has a white sticker in one of the corners that reads V1456VQH-R6NP1, then either one of these drivers SHOULD work for you, as this is what was printed on mine. I sincerely hope this helps others, as I have received help here as a result of other peoples' kindness in the past. One of the files (not sure which) contains and installation document that will help greatly. I wish you luck!
