Windows USB driver for
Diagnostic Interface 446 301 001 0
i.e. from Set 446 301 022 0
If a Diagnostic Interface with USB is connected to a PC with a Windows operating system 98, ME, XP or Vista
for the first time, it is necessary to install the driver software for this device. This procedure does not need to
be repeated the next time the Diagnostic Interface is connected.
The cable (included in delivery) is used to connect the Diagnostic Interface to the USB port of the PC and then
to the vehicle (switch on ignition!).
The Windows operating systems detects the Diagnostic Interface automatically and requests the software for
the new hardware component.
Should the workstation have more than one USB port, the installation routine must be repeated for each port.
The installation procedure is simplified once the driver has been installed for one USB port already (see page
4).
- Check the second radio button Install from a list or specific location (Advanced).
