USB Driver Installation Instructions for VCDS and Windows XP

Notes:  VCDS should install the drivers automatically. These instructions are only to be used in case the automatic driver installation is not successful. These instructions are for Windows XP.  Installation under Windows 98/ME/2000 is similar, but not necessarily identical.

  1. Make sure you have already downloaded and installed VCDS on your PC before following these instructions.
    If you haven't yet downloaded VCDS, then click HERE to open our download page in a new window.  

  2. Allow the software you just downloaded to install itself on your PC.  
    If you choose to install it someplace other than the default location,
    make a note of folder you're installing it to.

  3. Plug your Ross-Tech USB Interface to your PC's USB port (It is not necessary to connect the interface to a car yet). A message like this should appear on your PC's Taskbar:


       If the new Hardware Found Wizard popup does not appear when you plug in your interface, go into Device Manager and look for the interface. In Windows XP, you can typically find the Device Manager by RIGHT-CLICKING on My Computer then selecting Manage. Your Ross-Tech USB Interface should be under Universal Serial Bus (USB) Controllers or under Other Devices.    If it's there, Right-Click it and then select Update Driver.   Then you can start at Step 4 in the instructions below.    

  4. The New Hardware Found Wizard should appear:

  5. On the screen above, select "Install from a list or specific location (Advanced)"
    then click the [Next >] button.   

  6. The following dialog should appear:

  7. On the screen above:
    Select "Search for the best driver in these locations"
    Check "Include this location in the search:"
    Use the [Browse] button to find the VCDS folder
    (Usually C:\ross-tech\VCDS\
    unless you chose a different folder when you installed the software)
    Click [OK]

  8. The following dialog should appear:

  9. Click the [Next >] button.

  10. If you get a Windows message stating "This hardware will not be installed. Contact your system administrator" then you need to do the following

    A) Login to Windows with Administrator rights.

    B) Go into Start -> Settings -> Control Panel -> System -> Hardware -> Driver Signing

    C) Select Warn and choose "Prompt me each time to choose an action."

    D) Next, repeat the driver installation starting in Step 3.  

  11. The following dialog should appear:

    This dialog warns you that we haven't paid Microsoft a pound of flesh to certify the driver.
    You're going to have to click the [Continue Anyway] button..:-)   Note: If your Windows Security Settings policy is "undefined' you may need to set it to "warn" to be able to continue.

  12. The following dialog should appear:

  13. Click the [Finish] button to complete the installation.

  14. Start VCDS.
    Click the [Options] button.
    In the "Select COM Port" box, select USB.
    Click the [Test] button.
    The results should look like this (it may have additional information in the Port Test dialog).

  15. Click [OK] and click [Save]

  16. Go test it on a car.  :-)

Note: If you run into problems with this procedure (make sure to try the suggestions in step 3), feel free to Contact us while you are in front of your PC, connected to your vehicle.
