Do You Really Need a Driver?

Windows 10 & 11: In most cases, Microsoft includes a generic USB Mass Storage driver (USBSTOR.SYS) that works automatically. However, some advanced features (like DMA access or specific card types) may require the dedicated Alcor driver.
Windows 7, 8, 8.1: Manual driver installation is often required to get the card reader working properly.
Windows XP / Vista: You will almost certainly need the specific AU6370 driver.

2. How to Install the Driver

If your device is not being detected, follow these steps in order.

Step 2: Manual Installation (Legacy Method)

If automatic detection fails, you may need to install the driver manually.

Download the Alcor AU6370 driver package (often found on chipset driver repositories or the Alcor Micro website).
In Device Manager, right-click the unrecognized device and choose Update Driver.
Select Browse my computer for drivers.
Navigate to the folder containing the downloaded driver files (look for .inf, .sys, and .cat files).
Select the driver file and click Open.

Note: On Windows 10/11, Microsoft often blocks unsigned drivers from older hardware. You may need to restart your computer into "Advanced Startup" mode and select "Disable Driver Signature Enforcement" to install very old AU6370 drivers.

5. Summary

While the Alcor AU6370 is a reliable legacy controller, modern Windows users rarely need to hunt down a specific driver file.

For simple detection issues: Use Windows Update or Device Manager.
For "No Media" or capacity errors: You need the AlcorMP Mass Production Tool, not just a driver.
For hardware failures: If the device does not show up in Device Manager at all, the physical drive is likely damaged beyond software repair.

The Alcor AU6370 is a single-chip solution primarily used for USB smart card readers, frequently found in devices like the Lenovo ThinkPad Yoga 370. Drivers, such as version 1.7.46.0, are essential for enabling secure authentication and fixing hardware recognition issues on Windows 10 (64-bit). For more information, visit Softpedia.

When Do You Need This Driver?

In modern versions of Windows (Windows 10 and Windows 11), most USB mass storage devices are "plug-and-play." This means the operating system uses generic drivers to communicate with the device automatically. However, you may need to manually install Alcor AU6370 drivers in the following scenarios:

Device Not Recognized: The USB device is plugged in, but Windows displays "Unknown Device" or does not appear in File Explorer.
Corrupted Firmware: The flash drive is showing the wrong capacity (e.g., a 64GB drive showing as 0MB or 4MB) or requires formatting constantly. This usually requires the AlcorMP Utility, which relies on the driver to communicate with the controller.
Write Protection Errors: The drive has become read-only, and standard Windows formatting tools cannot fix it.

3. Driver installation fails with "Access Denied"

Fix: Disable Driver Signature Enforcement temporarily:
- Shift + Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → Press 7 (Disable driver signature enforcement). Then install the driver.

3. The Real Solution: AlcorMP Tool

If you are searching for a driver because your flash drive is showing up as "No Media" or has a capacity of 0 bytes, a simple driver will not fix it. The AU6370 likely needs to be "re-flashed."

Because the AU6370 manages the NAND flash memory, it requires a specific formatting utility known as AlcorMP (Alcor Mass Production Tool).
