I found no one seems to ever find such things. But here's where you would get such a driver. --> From the maker of the modem.
1- Would plan to ADD :
a NEW OS LEGEND = Windows CE version 6 ?
in Fact: there is new very small NetBook with Operating System Windows CE version 6 !
And, unfortunately: NO DRIVER inside to view & support Modem Key 3G+ with :
UMTS Data Card Huaewei E180
PC Kids VidoJet
Ref.5028 ( KS-UMPC070VA )
Windows Embedded CE 6.0 (C6G)
QC PASSED 09-2010
2- Would you a new "BUTTON" to permit to send you somme attached's File's ?
THANK YOU in advance from FRENCH COUNTRY, Michel .
