Root the pcDuino3 by installing SuperSU from the google play store.

Install ES File Explorer

Install the Terminal Emulator if it is not already.

Open terminal window and become a super user by executing “su” command.

Remount file system as writable by executing “busybox mount -o remount,rw /system”

Use ES File Explorer to create “android.hardware.usb.host.xml” into folder “/system/etc/permissions”. Edit the new file so that it contains the following…

<?xml version="1.0" encoding="utf-8"?>
<permissions>
<feature name="android.hardware.usb.host"/>
</permissions>

Edit file “handheld_core_hardware.xml” or “tablet_core_hardware.xml” in the same folder as above to include the line, “<feature name=”android.hardware.usb.host” />” inside  the permissions area denoted by “<permissions>” and “</permissions>”.

Reboot

You should now see your USB serial device when connected.e
