How to enable disabled USB accessories:

Let's explore effective solutions to get your USB accessories working again:

1. Reconnect Your USB Device:

This simple step often resolves minor connection issues.

1. Safely eject the device from your Mac.
2. Unplug the USB device.
3. Wait briefly (10-15 seconds).
4. Reconnect the device.

2. Direct Connection:

Bypass any hubs or adapters. Connect the USB device directly to a USB port on your Mac.

3. Restart Your Mac:

A simple restart can often resolve temporary software glitches.

1. Go to the Apple menu and select "Sleep".
2. Alternatively, use the keyboard shortcut Option-Command-Media Eject (or add the sleep button to your Touch Bar).

4. Reduce Connected Devices:

Unplug any unnecessary USB devices to ensure sufficient power for your essential accessories.

5. Try a Different Port:

Test your USB device in another USB port on your Mac.

6. Use a Different Adapter:

If using an adapter or hub, try a different one to rule out compatibility issues.

7. Update Drivers and Firmware:

Outdated drivers can cause compatibility problems. Check for updates via System Settings > General > Software Update.

8. Scan for Malware:

Malware can disrupt USB functionality. Use Activity Monitor to check for suspicious processes.

9. Reset SMC (System Management Controller):

This can resolve power-related issues. Hold Shift-Control-Option power button for 10 seconds, then restart your Mac.

10. Reset NVRAM (Non-Volatile RAM):

This resets certain system settings. Hold Option-Command-P-R during startup until you hear the startup sound twice.
