问题 I'm going to run Android app on Chromebook directly to access connected usb devices, not from ARC Welder. I want to use ES File Explorer to access my usb devices.

问题 This emerged out of an earlier question Android app on Chromebook to access USB devices? It seems that ARC does not yet provide any way to access external storage except using { "enableExternalDirectory": true } . This has some significant limitations for my use case.

Unfortunately, with the enableExternalDirectory option enabled, the user is forced to select a directory, even

问题 Android has implemented the USB host mode in Android 3.1 and newer. I've gone through documents in the following link: http://developer.android.com/guide/topics/connectivity/usb/index.html http://developer.android.com/guide/topics/connectivity/usb/host.html However, the information provided by Android official website is relatively too high level for me to understand the whole story. I know that OTG is necessary to implement USB host mode. I have some questions listed in the following: How

I was thinking to create a second little hidden partition in the drive and locate in it as a name the serial obteined by the PNPdeviceID or
