The android.hardware.usb.host.xml file is open-source under the Apache 2.0 license. You are free to download, modify, and redistribute it. However, bypassing manufacturer restrictions on USB host mode may void your warranty. In 2021, several manufacturers (notably Huawei and some low-end Mediatek tablets) deliberately removed this file to segment their product line. Enabling it is not illegal, but it is unsupported.
In mid-2021, MIUI 12.5 and OxygenOS 11.0.5.1 had a bug where the system deleted android.hardware.usb.host.xml after every OTA update. Users had to create a survival script in Magisk to re-copy the file after each reboot.
Yes and no.
git clone https://android.googlesource.com/platform/frameworks/base
cd base
git tag --list | grep "android-11" # find 2021-era tags
git checkout <tag-from-2021>
# then search for the XML
grep -R "androidhardwareusbhost.xml" -n .
Cause: The system partition on Android 10+ uses dm-verity and file-based encryption. Even with root, changes are lost on reboot unless you disable verity.
Solution: Run adb disable-verity before remounting, or use a Magisk module.
Even though the search term specifies "2021" , the file remains largely unchanged in Android 13, 14, and 15. The 2021 versions correspond to the Android 11 and 12 eras, which were pivotal for USB changes (e.g., the switch to a more secure USB stack). If you find a copy from a 2021 AOSP tag, it is still perfectly compatible with modern Android versions. androidhardwareusbhostxml file download 2021
Final Checklist:
By following this guide, you should be able to successfully download, install, and activate USB Host mode on your Android device, just as developers and power users did throughout 2021 and beyond. The android

This topic often arises when developers or advanced users try to manually enable USB Host mode (OTG support) on rooted Android devices or custom ROMs where the feature is not automatically recognized. In mid-2021, MIUI 12
Cause: system partition is dm-verity protected.
Solution: Disable dm-verity via fastboot: fastboot disable-verity. On newer devices, create a Magisk module instead of modifying /system directly.
