Connect the Device: Plug your Delphi DS150E into a USB port on your PC.
Open Device Manager: Right-click the Start button and select Device Manager.
Locate the Device: Find "Autocom CDP+ USB" or "Delphi VCI" under Other devices (it will likely have a yellow exclamation mark). Update Driver: Right-click the device and select Update driver. Choose "Browse my computer for drivers".
Click Browse and navigate to your Delphi software installation folder (e.g., C:\Delphi\Drivers).
Repeat for Serial Port: After the VCI driver is installed, a second entry for "USB Serial Port" may appear. Repeat the steps above for this entry to ensure full functionality. 3. Verification & Testing delphi 100 251 rev 10 driver download new
Once installed, you must link the hardware to your software: Launch your Delphi diagnostic software. Go to Settings > Hardware Setup.

Let’s assume you downloaded the official FTDI driver.
Critical Warning About Drivers from Untrusted Sources
Many websites claiming to offer "Delphi 100 251 rev 10 driver download" are:
- Outdated (Windows XP/7 era drivers)
- Infected with malware or unwanted software
- Fake — they lead you through surveys or downloads that don't work
Step 1: Remove old or corrupt drivers
- Open Device Manager.
- Under Universal Serial Bus controllers, look for any greyed-out or error-icon entries named "USB Serial Converter" or "Delphi".
- Right-click → Uninstall device → Check "Delete the driver software for this device".
- Repeat until no Delphi/FTDI entries remain.

Step 4: Connect the Delphi 100 251 Rev 10
- Plug the device into a USB 2.0 port if possible (USB 3.0 sometimes causes latency).
- Device Manager should refresh and show under Ports (COM & LPT) as "Delphi DS100E (COM3)" or "USB Serial Port (COMx)".
Q2: My device shows as "FT232R USB UART" – is that correct?
Yes. That means the generic FTDI driver loaded, but not the Delphi-specific one. To fix: Right-click that entry → Update driver → Browse my computer → Let me pick → Select "Delphi DS100E" from the list (if present). If not, reinstall the Delphi custom INF from their support site.
What You May Actually Be Looking For
The number sequence "100 251" resembles part numbers for Delphi diesel fuel injection components (e.g., injectors, control valves, or ECU-related parts). "Rev 10" indicates a revision level of a hardware component. If you need a driver, it's likely for:
- A diesel diagnostic interface (e.g., Delphi DS150E, Autocom CDP+)
- A Chinese clone diagnostic tool using Delphi software
- An old vehicle communication interface
