    This is a very common bugcheck. Usually the exception address pinpoints
    the driver/function that caused the problem. Always note this address
    as well as the link date of the driver/image that contains this address.
    Arg1: c0000005, The exception code that was not handled
    Arg2: b6439fce, The address that the exception occurred at
    Arg3: f3b96c40, Exception Record Address
    Arg4: f3b9693c, Context Record Address

    Debugging Details:

    EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at "0x%08lx" referenced memory at "0x%08lx". The memory could not be "%s".

    Ideally if you have the option for ethernet on that Alcatel modem, use that
    Then uninstall the USB drivers through add\remove programs

    I'm only concerned what's plugged into the computer (ie after this conversation - ethernet ;) )
