I've been troubleshooting the issue of SideQuest not detecting Oculus Quest 2, and here's a summary of effective solutions:

Reconnect USB Cable: Unplug and then reconnect the USB cable while ensuring the headset is on. Enable Developer Mode: Verify developer mode is enabled in the Oculus app with the same account used on the headset. Allow USB Debugging in Headset: When connecting to SideQuest, approve the USB debugging prompt in the headset. Enable USB Connection Dialog in Headset: In Quest 2 settings, ensure "USB Connection Dialog" is enabled under Developer settings. Check ADB Drivers: Confirm that ADB drivers are installed and updated correctly on your PC. Try Different USB Ports: Test various USB ports on your PC in case of port-specific issues. Try a Different USB Cable: Use another USB-C cable to check for cable-related problems. Reinstall SideQuest: Uninstall SideQuest, delete leftover files, and reinstall it to resolve potential software issues. Try SideQuest on Another PC/Android Device: Install SideQuest on a different PC or an Android device to check device-specific issues.

These methods are usually effective in resolving the connection problem between Oculus Quest 2 and SideQuest. Feel free to check out my post for more details on any of these fixes!
