. If you’ve lost your CD, you can often find the download on the Siemens Support Portal or hosted on community sites like PLC ONE. 2. Installation Steps (The "Clean" Method)

To avoid the common "installation stopped" error, follow this sequence:

Run as Administrator: Right-click the Setup.exe from the driver folder and select Run as... then choose the Administrator account.

Install Prerequisites: The setup will install the Microsoft Visual C++ 2005 Redistributable first. If you aren't in an Admin session, it may hang here.

Restart First: Once the "Simatic Device Drivers" are installed, restart your PC before plugging in the adapter.

Hardware Wizard: Plug in the USB cable. When the "Found New Hardware Wizard" pops up, select "No, not this time" for Windows Update, then "Install the software automatically". 3. Configuration & Troubleshooting

Set PG/PC Interface: Open your communication settings and ensure "PC Adapter USB A2" is selected.

Virtual Machines: If you're running XP in a VM (like VMware or VirtualBox), make sure your USB controller is set to USB 2.0 compatibility; users have reported that USB 1.1 settings often cause internal errors.

Verify in Device Manager: You should see "Simatic PC Adapter USB A2" listed under Simatic Net without any yellow exclamation marks.

Driver Version Compatibility

Ensure you are using a driver version compatible with your hardware revision.

Original PC Adapter USB: Older drivers work fine on XP.
PC Adapter USB A2: This is the newer revision. It requires newer drivers (usually included in STEP 7 5.5 SPx). If you are using an older STEP 7 version (like 5.4) with a newer A2 adapter, you may need to manually download the updated driver pack from Siemens Support, as the files on the original CD may not support the A2 revision.

Method 3: Use USBDeview (Free tool)

A small utility from NirSoft that gives exhaustive USB information, even without drivers installed.

Once you have the VID/PID, search Google for “Windows XP driver VID_xxxx PID_yyyy” – this yields specific, safe results.

The Ultimate Guide to the PC Adapter USB A2 Driver for Windows XP: Installation, Troubleshooting, and Legacy Support

For USB-to-Serial (Prolific PL-2303):

Important: Prolific deliberately broke older chips on newer drivers. Use version 3.3.2.105 (dated 2008) for genuine “A2” adapters.
Follow the “Have Disk” method as above. After installation, you’ll see a new COM port under “Ports (COM & LPT)”.

Part 1: What Exactly is a "PC Adapter USB A2"?

First, let’s demystify the name. "PC Adapter USB A2" is not a universal standard; it is a generic label often printed on low-cost USB dongles manufactured in the mid-2000s. The "A2" typically refers to a chipset revision or a product batch number.

The most common devices bearing this label fall into three categories:

USB 2.0 to Ethernet Adapters – Used to add a wired network port to a laptop or desktop without one.
Bluetooth 2.0 + EDR Dongles – Enabling wireless file transfer, mouse, and keyboard connectivity.
USB-to-Serial (RS232) Converters – Essential for industrial equipment, CNC machines, or old printers.

Crucially, Windows XP does NOT include native drivers for these adapters. Unlike Windows 10 or 11, which often auto-detect and install generic USB drivers, Windows XP relies on third-party drivers provided by the chipset manufacturer.

The primary chipset vendors responsible for “A2” variants include: Original PC Adapter USB: Older drivers work fine on XP

C-Media (for audio/USB combo adapters)
Realtek (for Ethernet adapters – RTL8150, RTL8152)
Cambridge Silicon Radio (CSR) (for Bluetooth dongles – BlueCore 2)
Prolific (for USB-to-Serial – PL-2303)

Thus, searching for “pc adapter usb a2 driver windows xp” typically leads you to drivers for one of these chipsets.

Step 2: Connect the Hardware

After the reboot, log in to Windows XP.
Plug the PC Adapter USB A2 into an available USB port.
Windows XP will detect the new hardware. In the bottom right corner, a "Found New Hardware" balloon will appear.
Because you pre-installed the drivers, Windows XP should automatically locate the drivers without asking for manual input. It will display a message saying "Your new hardware is installed and ready to use."

Part 4: Where to Download the Driver Safely (2026 Update)

Given the age of XP, avoid pop-up-ridden “driver download” sites. Instead, use these reliable sources:

Chipset Manufacturer’s Archive (if still online):
- Realtek: www.realtek.com → Downloads → Legacy LAN drivers (search for “XP”).
- Prolific: www.prolific.com → Support → Downloads (look for PL-2303 XP driver v3.3.2.105 – the last stable version).
- CSR Bluetooth: Harder to find; use GitHub’s driver archive or driver.gtplanet.net.
The Internet Archive (Wayback Machine) – Search for the original CD image of the adapter.
DriverPacks.net – A trusted offline solution: “DriverPack LAN XP” includes most USB Ethernet drivers.
Older Hardware Communities – VOGONS (for gaming) and MSFN (for Windows XP enthusiasts) have verified driver repository threads.

Never download .exe files from sites like driver-solution.com or my-driver.net – they are often malware that XP’s outdated security cannot block.

Part 10: The Final Resort – Extracting Driver from Original CD

Many “PC Adapter USB A2” devices shipped with a mini-CD. If you lost it, check secondhand markets (eBay, local listings). People often sell just the CD for a few dollars.

Once you have the CD:

Explore the disc in Windows XP.
Look for folders named “DRIVER”, “WINXP”, or “A2”.
Run Setup.exe (usually in Win32 or XP folder).
If no installer, use the “Have Disk” method pointing to the .inf files.

Pro tip: Copy the entire CD to a folder on your hard drive – the original media might be unreadable soon due to disc rot.
