I want to use the USB-WIFI adapter TL-WN725N on a Colibri VF61 module with the Linux Image 2.7.
The adapter use the RTL8188EUS chip set and is supported out-of-the-box (High performance, low power Embedded Computing Systems | Toradex Developer Center).

How can I install the driver on the module?
How can I add the driver to the image?

I’ve noticed you’re running dirty kernel. Have you compiled and deployed kernel and backports modules? Have you tried using your usb wifi adapter with our stock image ( link )?

With the stock image the usb wifi adapter works.
What is the minimal configuration to compile the backports for the usw wifi adapter?
