Are you sure it's not a CX93010 modem?
Compatible with Windows 98 / 2000 / XP / ME / NT4.0 vista/windows7
it appears to be a no-name brand modem and I can't find much on it. Might be better off getting a name brand modem that you know you can use. Does it ave to be a USB modem? you can pick up a brand new modem for around $15.
