Worth trying:

ftp://ftp.panasonic.com/pub/Panasonic/toughbook/downloads/WWAN/software/MC7750_VZAccess_Manager_7-7-1-12-2763b.zip
ftp://ftp.panasonic.com/pub/Panasonic/toughbook/downloads/WWAN/software/MC7750_QMIDriverPackage_Build3644_Win7.zip
ftp://ftp.panasonic.com/pub/Panasonic/toughbook/downloads/WWAN/Firmware/MC7750_Firmware_3_5_10_9.zip

or http://www.vzam.net/Download/Download.aspx and pick something with
MC7750 in it.
