how to let wifi adpate work with beagleboard based on Android

I am now using Beagleboard based on Android 4.1.*, but it can not support wifi.

I bought the wifi usb adpater which integrates the chipset: RLT81188CUS, and I down some files from its webside.

But, now I have no idea how to let this wifi adaper work when connecting with my android-based beagleboard? need to compile? and How?

I hope to let this android-based beagleboard can access wifi via this adapater.

Appreaciate for anyone who can give me some instructions about it, great thanks.
