    You can use this procedure
    my ditty - search for drivers by HardwareID - TenForums

    It might be quicker to figure out what hardware the students have installed and search for its support website.
    It might well be a mobile phone connection or an internal SIM card.


    Best of luck,

    Hello Try3,
    The students they cant install anything and the system is clean.
    Yes it is an internal sim card adapter for mobile phone connection.

    I think it is a Marvell chip but i cant identify witch one.

    Thanks for help

    Moreiras,

    So you are now going to search for its driver by using its HardwareID, I assume.


    Best of luck,
