The drivers many install automatically in Windows 7 or Vista. If you are using XP or W2000, click on the Found New Hardware message and the Found New Hardware Wizard should start up. If you are prompted with the choice, pick “No, Not This Time” when asked if you want to connect to the Internet to search for drivers. Select “Install the software automatically (Recommended)” then click [Next >]
The process should be automated but you may need to click “Continue Anyway” part way through the process.

If, for some reason, you installed the USB Interface without following the above instructions, and VCDS does not work correctly, go into your PC’s Device Manager while the USB Interface is connected.

You can find the Device Manager by right-clicking on My Computer in XP or on Computer in Vista or 7. Select Manage to bring up Computer Management. On the left side of the screen under System Tools, select Device Manager.

Find the “VCDS Compatible USB Interface” or similar and delete it. It may be under “Other Devices” or under “Universal Serial Bus Controllers”. Next, unplug the USB Interface from your PC, wait 5 seconds and plug it back in.

 

Connect the car end of your Interface to your vehicle’s Diagnostic Port.

If the Interface Status is “Not Found!”,check the connections at the car and PC.Make sure both are plugged in securely.Serial Interfaces get their power from the vehicle so they will not be recognized at all if not plugged into a car.
Adapter Type should always be “RossTech” followed by the name of the Interface such as “HEX-USB+CAN”.
Version indicates the firmware version of your Interface. It may be updated by new versions of VCDS, if so follow the prompts on the screen.
