MS/MS-Pro Driver

The MS/MS-Pro driver helps Windows communicate with compatible Memory Stick and Memory Stick PRO card-reader hardware so you can access files on supported memory cards. Listed under Microsoft in the Other device category, this entry may be relevant if your reader appears as MS/MS-Pro in Device Manager, is not recognized, or cannot read a compatible card. Before downloading, confirm that the driver matches your reader’s hardware ID and Windows version.

Key Features

• Card-reader communication: Enables Windows to work with matching MS/MS-Pro reader hardware and access supported Memory Stick media.
• File access: Supports normal file-management tasks, such as opening, copying, and transferring files, when the reader and card are functioning correctly.
• Device recognition: A compatible installation may resolve a missing-driver warning or an unidentified MS/MS-Pro entry in Device Manager.
• Legacy Windows coverage: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Package compatibility can vary, so check the supported version and architecture before proceeding.

How to Install MS/MS-Pro Driver

1. Identify your reader. Open Device Manager and locate the MS/MS-Pro entry, which may appear under Other devices. Open Properties, select the Details tab, and choose Hardware Ids to help verify the correct driver.
2. Check compatibility. Before choosing an MS/MS-Pro driver download for Windows, confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, do not assume that a Windows 10 package also supports Windows 11; verify compatibility separately.
3. Choose a trusted package. Look for the latest version compatible with your specific hardware, preferably through Windows Update or the reader or computer manufacturer. If a free download is offered, check its source and compatibility details rather than relying on the device name alone.
4. Install the driver. Run the supplied installer, if available. For an extracted driver package, right-click the reader in Device Manager, select Update driver, and browse to the folder containing the driver files.
5. Test the reader. Restart if prompted, then insert a known-working, compatible memory card. Check that it appears in File Explorer and that files can be opened.

Keep the driver updated through trusted sources, especially when troubleshooting recognition problems or after a Windows upgrade. An update should match your hardware and operating system; a newer package is not automatically a better fit for an older reader.
