Important: Please read the Qt Code of Conduct -


  • Hey guys,

    I am developing a USB HID app that would require host connection to the USB device on Android. I am using LIBUSB. The phone is able to detect the device but unable to connect (open) it, and the error returned is LIBUSB_ERROR_ACCESS.

    Is there any Qt library that would handle access USB permissions on Android? The library should only prompt for permission once and that would be it.
