It looks like you're looking for a specific file named android.hardware.usb.host.xml, likely for enabling USB host mode (OTG support) on an Android device or custom ROM (e.g., LineageOS, AOSP).
Instead of downloading an unknown file, you can create the correct file yourself with the exact code the Android system requires. Open your File Manager and grant it root access. Navigate to the directory: /system/etc/permissions/ androidhardwareusbhostxml file download 2021
What changed in 2021?
In previous Android versions (9/10), the file sometimes included additional permissions like <feature name="android.hardware.usb.accessory" />. However, Google’s 2021 CDD (Compatibility Definition Document) separated these. The clean, minimal version above is the correct one for 2021 standards. Using an older file could cause conflicts with Android 11’s scoped storage or USB accessory detection. feature name="android.hardware.usb.accessory" />

Developers porting Android 10/11 ROMs to older hardware in 2021 often needed to pull this file from a working device or from AOSP source code.
