modem driver for Sportster Vi

I’ve got a Win95 machine that detects my internal modem as a US Robotics Inc. Sportster Vi 28.8 Voice Fax Internal, trouble is I cannot find a driver that works! I looked on driverguide.com and 3Com’s web sites and found something that looked like it matched, but when I tried to use it, Win95 told me that it could not find the necessary files. The FCC ID number is: CJE-350, the FCC REG. NO. is: CJEUSA-20778-MM-E. Does anyone have the correct driver for this modem?? Thanks much for the help!
