The Autocom CDP+ diagnostic tool requires proper FTDI-based USB drivers, often located in the software installation directory (e.g., C:\Program Files (x86)\Autocom\Cars CDP+\Drivers
), to function with PC-based diagnostic software. Proper installation involves connecting the device, using Device Manager to update drivers, and ensuring the device is recognized as an Autocom USB Serial Port to avoid communication errors or firmware update failures.

The story of the "Autocom CDP+ USB Driver software" thread on MHH AUTO is not just a story about installing a piece of software. It is a chapter from the "Golden Age" of independent automotive diagnostics—a tale of guerrilla warfare between Chinese hardware clone manufacturers and Western software developers, played out on internet forums.
Here is the long story behind that specific, legendary thread.
If you have landed here, you are likely staring at a blinking red LED on your Autocom CDP (Cars Diagnostic Pro) unit, or your computer is refusing to recognize the hardware. You’ve searched for "autocom cdp- usb driver software - MHH AUTO - Page 1" , which means you know exactly where the collective intelligence of diagnostic technicians resides: the legendary MHH AUTO forum. autocom cdp- usb driver software - MHH AUTO - Page 1
This article serves as a comprehensive guide. We are going to dissect everything you need to know about finding, installing, and troubleshooting the USB driver software for the Autocom CDP 2010, 2011, and 2013+ units, specifically referencing the "Holy Grail" knowledge found on MHH AUTO Page 1.
When you download the authentic package from the MHH thread, you will find three critical components:
Link reference for the article: Navigate to MHH AUTO -> Diagnostic Hardware Section -> Autocom/Delphi -> Look for the sticky titled "Autocom CDP 2013 USB Drivers Working Win10/11 - Page 1".
The first page of that thread is a microcosm of the entire industry. It usually begins with a desperate plea from a user named something like GearHead99 or WrenchTurner.
"Hi friends. I bought a CDP+ interface. I installed the 2013.3 software, but the USB is not working. The device manager shows a yellow exclamation mark. Can anyone help?" Link reference for the article: Navigate to MHH
This simple request triggers a cascade of responses that outlines the technical hierarchy of the forum:
1. The Purist Response: First, usually a senior member chimes in: "You are using a clone. It is trash. Buy a genuine tool." This was the constant tension on MHH AUTO—elitists vs. the budget mechanics. But for a mechanic in a third-world country or a small-town shop, a $3,000 tool wasn't an option.
2. The "Old Guard" Tech Support:
Then, the real help arrives. Veteran members who understand the deep architecture of the device reply. They explain that the issue isn't just the driver file (.sys or .inf), it's the Bootloader.
The clone devices often used a generic microcontroller to emulate the genuine Autocom hardware. To make the driver work, the user didn't just need a driver; they needed to force the firmware onto the device.
3. The Fix (The "Finger Dance"): This is where the thread becomes legendary. Someone eventually posts a link to a hacked driver pack—usually hosted on a file-sharing site like Mega.nz or Mediafire (which are often dead links by Page 10). They explain the "Finger Dance" technique:
Most solutions found on forum threads revolve around a manual installation process. Here is the general procedure that is often discussed in those "Page 1" threads: "Hi friends
The Autocom CDP hardware was manufactured in an era of Windows XP and Windows 7. The USB drivers use an old digital certificate that Microsoft no longer trusts by default. If you simply plug in your CDP, Windows 10/11 will flag the driver as "unsigned" and refuse to load it, resulting in the dreaded "Device descriptor request failed" error.
The solution? The specific driver package found on MHH AUTO Page 1.
Some CDP+ drivers allow a “mode switch” utility to toggle between:
If your driver lacks this, you may need MHH Auto user tool like “CDP_Switch.exe”.
Windows 7, 8, 10, and 11 enforce driver signing. The original Autocom CDP drivers (circa 2010-2014) are unsigned or use obsolete certificates. When you plug the CDP into a USB port on a new laptop, Windows simply ignores it or slaps a yellow exclamation mark in Device Manager.
This is where MHH AUTO enters the story.
