USB Port Not Working on ASUS VivoBook S 16 OLED
The USB ports on the ASUS VivoBook S 16 OLED are controlled by the AMD USB xHCI host controller built into the Ryzen 7 7730U chipset. When the AMD chipset driver is outdated or corrupted, connected USB devices may not be recognised even though the hardware is intact.
Fix 1 — Run the Windows USB Troubleshooter Most common fix
Open Settings, go to System, Troubleshoot, then Other troubleshooters. Run the Hardware and Devices troubleshooter. It scans for USB device detection failures, power issues, and driver conflicts. Apply any fixes it suggests and test the port again.
Fix 2 — Update AMD Chipset Driver
Go to asus.com/support and download the AMD Chipset driver for VivoBook S 16. This package updates the AMD USB xHCI controller driver. Run the installer as administrator and restart. After reboot, plug a USB device into the non-working port to test.
Fix 3 — Disable USB Power Management
Open Device Manager and expand Universal Serial Bus controllers. Right-click each USB Root Hub and go to Properties, then Power Management. Uncheck Allow the computer to turn off this device to save power. This prevents USB ports from being suspended when the laptop runs on battery.
Fix 4 — Reinstall USB Controllers
In Device Manager, expand Universal Serial Bus controllers and right-click each USB controller entry. Choose Uninstall device. After removing all entries, restart the laptop. Windows will automatically reinstall USB controllers from scratch during boot. This clears any corrupted driver state that was blocking device detection.
Common questions
Is it a dead port or a driver issue?
Test with two different USB devices. If neither is detected, it is likely a driver or power issue rather than a dead port.
Which port is USB 3.2 vs USB 2.0?
The blue or teal USB-A port is USB 3.2 Gen 1. The black port is USB 2.0. High-speed devices may not work on the 2.0 port.
Does MyASUS help with USB issues?
Yes. Open MyASUS and run a System Diagnosis scan. It checks USB controller status and flags driver issues automatically.
