Socket USB-Serial Adapter (COM4) Driver

The Socket USB-Serial Adapter (COM4) driver lets Windows communicate with compatible serial equipment through your Socket USB adapter. It is needed when setting up the adapter for the first time, restoring a missing COM port, or troubleshooting a serial connection that your software cannot detect.

Key Features

• USB-to-serial communication: Provides the driver support needed to connect compatible serial devices through a USB port.
• COM port access: Makes the adapter available to applications that communicate over a serial port. COM4 is the current port assignment shown in the device name; Windows may assign a different number after installation.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, with the appropriate package selected for your operating system and architecture.
• Device configuration: Allows Windows to recognize and manage the adapter so you can select its COM port and configure supported serial settings in your application.

How to Install Socket USB-Serial Adapter (COM4) Driver

1. Check your system and adapter. Confirm your Windows version and whether it is 32-bit or 64-bit. If multiple Socket adapters are listed, compare the device’s hardware IDs in Device Manager with the package documentation.
2. Choose the correct package. Before starting your Socket USB-Serial Adapter (COM4) driver download for Windows, check the supported systems and adapter models. For Windows 10/11 users, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed here.
3. Download and extract the files. Choose a trusted source for a free download, and select the latest version explicitly compatible with your adapter and Windows release. Extract the archive if necessary.
4. Install the driver. Follow the included setup instructions. If no installer is provided, open Device Manager, locate the adapter or unidentified USB device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, then check Ports (COM & LPT) in Device Manager. Select the assigned COM port in your serial application and match its communication settings to the connected equipment.

Keep the driver updated when a compatible release addresses connection problems or supports a system change. Before you update a working installation, review the package notes and retain the previous installer so you can restore your existing setup if needed.
