The LG GW550 WinMobile Diagnostics (COM163) driver helps Windows recognize the LG GW550’s USB diagnostic interface and make it available to compatible service software through a COM port. This Qualcomm Atheros-listed USB driver is intended for users who need diagnostic communication with the handset, particularly when Device Manager shows an unrecognized interface or a driver warning.
Key Features
- Diagnostic USB connectivity: Provides the Windows-side interface needed for compatible diagnostic tools to communicate with the phone.
- COM-port recognition: Identifies the diagnostic connection as a serial port. COM163 is the port assignment in this device name; Windows may assign a different number on another computer.
- Legacy Windows support: Listed for Windows 10, 8.1, 7, Vista, and XP. Check the individual package for your Windows version and system architecture before installing.
- Targeted device support: Addresses the diagnostic interface rather than serving as a general-purpose driver for file transfers, charging, or every LG phone function.
How to Install LG GW550 WinMobile Diagnostics (COM163) Driver
- Check your system. Confirm your Windows version and whether it is 32-bit or 64-bit. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supplied support list.
- Choose the appropriate package. Before starting the LG GW550 WinMobile Diagnostics (COM163) driver download for Windows, verify that the package matches your device and operating system. For any free download, check the source and scan the file before opening it.
- Prepare the connection. Extract the downloaded archive if necessary, then connect the phone using a working USB data cable. The handset must expose its diagnostic interface for Windows to detect it.
- Install the driver. Run the included installer if one is provided. Otherwise, open Device Manager, locate the diagnostic or unknown device, select Update driver, and browse to the extracted driver folder.
- Verify detection. Reconnect the handset or restart Windows if prompted. Check Device Manager for the diagnostic port and select its assigned COM number in your compatible service application.
Keep the driver updated when a verified, compatible release addresses a connection problem or improves support for your setup. The latest version is only useful if it supports this specific interface and your operating system; avoid replacing a working driver with an unrelated package simply because it appears newer.
