Right-click the Windows Start button and open Device Manager . Find any item listed as "MI4" or "Unknown Device". Right-click it, choose Uninstall Device , and check the box that says "Attempt to remove the driver for this device".

The last official Windows drivers for the Steinberg MI4 (version 2.8.45) date back to around the Windows Vista/7 era. Because modern Windows 10 architecture handles USB audio class compliance and driver signing much differently, plugging in the MI4 and running the legacy installer will often result in the device not being recognized, failing to migrate, or causing audio dropouts.

Even if you get the MI4 working, you might encounter other common hardware issues.

Go to Control Panel > Power Options > Change plan settings > Change advanced power settings . Find the USB settings branch and set USB selective suspend setting to Disabled . This prevents your computer from cutting power to the MI4 during idle periods.

Note: If your MI4 unit has physical phantom power switches, this is not an issue. Using ASIO4ALL for Better Performance

Despite this, it is entirely possible to resurrect and stabilize your MI4 on a Windows 10 machine by following the workarounds outlined below. Step 1: Pre-Installation Preparation

: Open the Windows Start menu, type "Advanced system settings," and open the menu. Under the Performance section, click "Settings." Go to the "Advanced" tab and ensure that "Adjust for best performance of:" is set to Background services . This gives your ASIO audio drivers processing priority over the visual user interface.

Open the ASIO4ALL control panel interface from within your DAW or from your Windows system tray.

When deciding whether to try these workarounds, it's worth considering if the MI4 is still relevant. Some users have praised its high-quality preamps and robust build, but it's an old device. Modern interfaces like the Steinberg UR series offer comparable or better specs, are officially supported on Windows 10 and 11, and often include new features like loopback audio or MIDI I/O—all at a reasonable price point.
