Ricoh PCIe Memory Stick Host Controller Driver

The Ricoh PCIe Memory Stick Host Controller driver enables Windows to communicate with the Ricoh controller used by a computer’s Memory Stick card reader. You may need it after reinstalling Windows, when compatible Memory Stick media is not detected, or when Device Manager shows a missing driver for the controller.

Key Features

• Provides the driver support Windows needs to recognize and use the Ricoh PCIe Memory Stick controller.
• Enables access to files on compatible Memory Stick media through the computer’s built-in reader.
• Helps resolve recognition problems caused by a missing or incorrectly installed controller driver.
• Supports installation on compatible systems running Windows 10, 8.1, 7, Vista, or XP, depending on the driver package and hardware configuration.

How to Install Ricoh PCIe Memory Stick Host Controller Driver

1. Identify your hardware and Windows version. Open Device Manager, locate the Ricoh controller or unidentified device, and check its hardware IDs under Properties > Details. Also confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a compatible package. Before starting a Ricoh PCIe Memory Stick Host Controller driver download for Windows, verify that the package matches your computer model, controller, and operating system. Choose the latest version approved for your hardware, rather than assuming the newest package works on every PC.
3. Download and extract the files. Use a trusted free download from your computer manufacturer or another verified source. If the package is compressed, extract it to an accessible folder and review any included instructions.
4. Install the driver. Run the supplied installer, or use Device Manager’s driver update option to browse to the extracted driver folder. Follow the prompts and restart your computer if requested.
5. Test the card reader. Insert a known-working, compatible Memory Stick and check whether it appears in File Explorer or Windows Explorer. If it remains undetected, check the card, reader, and driver match before reinstalling.

Keep the driver updated when a compatible release addresses a problem or your computer manufacturer recommends an update. For Windows 10/11 systems, check compatibility carefully: Windows 10 support does not establish Windows 11 support, and Windows 11 is not among the listed supported operating systems for this device. If the reader already works reliably, avoid replacing its driver with an unverified package.
