Name: Kozumi K 300MWU Driver
Author: Kozumi

Question 1

Install fails or exits early?

Accepted Answer

Run the setup as administrator and use Windows compatibility mode if the package is older. Temporarily disable antivirus, unplug the adapter during setup, then plug it in when prompted.

Question 2

Device not detected?

Accepted Answer

Try a rear USB 2.0 port directly on the PC, not a hub or front-panel port. Check Device Manager for an unknown device or yellow warning, then reinstall the driver and rescan hardware.

Question 3

Version conflicts?

Accepted Answer

Uninstall any previous Kozumi utility and older Wi-Fi adapter drivers first. If Windows keeps loading a built-in driver, remove the device in Device Manager, reboot, and install the Kozumi package before reconnecting the K 300MWU.
