Device Permission Setup

Android and UWP both require that you specify which devices you will need to access in their manifest files. This is because Store apps are secure and won't let a given app access devices without the user's knowledge.

Here is an example Capabilities section for Hid and USB on UWP:

  <Capabilities>
    <Capability Name="internetClient" />

    <uap:Capability Name="removableStorage" />

    <DeviceCapability Name="humaninterfacedevice">

      <Device Id="vidpid:534C 0001">
        <Function Type="usage:0005 *" />
        <Function Type="usage:FF00 0001" />
        <Function Type="usage:ff00 *" />
      </Device>

      <Device Id="vidpid:1209 53C0">
        <Function Type="usage:0005 *" />
        <Function Type="usage:FF00 0001" />
        <Function Type="usage:ff00 *" />
      </Device>

      <Device Id="vidpid:1209 53C1">
        <Function Type="usage:0005 *" />
        <Function Type="usage:FF00 0001" />
        <Function Type="usage:ff00 *" />
      </Device>

    </DeviceCapability>

    <DeviceCapability Name="usb">

      <!--Trezor Firmware 1.7.x -->
      <Device Id="vidpid:1209 53C1">
        <Function Type="classId:ff * *" />
      </Device>

    </DeviceCapability>

  </Capabilities>
