How to Fix USB Library Version 03:02:07 Error in VCDS

VCDS is a software that allows you to diagnose and modify your Volkswagen Group vehicles. It requires a compatible interface cable that connects your PC to your car's OBD-II port. However, some users have reported an error message when trying to use VCDS: "Ross-Tech USB interface not found. USB library version 03:02:07 Interface NOT Found!" This error means that VCDS cannot communicate with the interface cable, either because the cable is faulty, the USB driver is missing or corrupted, or the PC's security software is blocking the connection. In this article, we will show you some possible solutions to fix this error and get your VCDS working again.

Solution 1: Check the Interface Cable

The first thing you should do is to check if your interface cable is working properly. Make sure it is connected securely to both your PC and your car's OBD-II port. You should see a green LED on the cable when it is powered on. If you have a HEX-V2 interface, you should also select the USB port option in VCDS. If you have a different interface, you should select the appropriate COM port option in VCDS. If the LED on the cable does not light up, or if it flashes red or yellow, it means there is a problem with the cable. You should contact Ross-Tech for support or replacement.

Solution 2: Update or Reinstall the USB Driver

If the cable is working fine, but VCDS still cannot find it, it means there is a problem with the USB driver on your PC. The USB driver allows your PC to recognize and communicate with the interface cable. You should make sure you have the latest version of VCDS installed on your PC, as it includes the latest USB driver. If you already have the latest version of VCDS, or if updating VCDS does not solve the problem, you should try reinstalling the USB driver manually. To do this, follow these steps:

Open Device Manager on your PC. You can do this by right-clicking on the Start menu and selecting Device Manager.

Look for Ross-Tech Direct USB Interface under Universal Serial Bus Controllers. If you see a yellow exclamation mark next to it, it means there is a problem with the driver.

Right-click on Ross-Tech Direct USB Interface and select Uninstall Device. Confirm by clicking Uninstall.

Disconnect and reconnect your interface cable to your PC. Windows should automatically detect and install the driver for it. If Windows does not install the driver automatically, you can manually install it by running DPInst.exe from C:\\Ross-Tech\\VCDS folder.

Restart your PC and try using VCDS again.

Solution 3: Disable or Configure Your Security Software

If none of the above solutions work, it means there is a problem with your PC's security software. Some antivirus or firewall programs may interfere with the connection between VCDS and the interface cable. You should try disabling or configuring your security software to allow VCDS to access the USB port. You can also add VCDS as an exception or trusted program in your security software settings. Refer to your security software's documentation or support for more details on how to do this.
