How do I force USB debugging? I am trying to figure out why my apps don't work on tablets manufactured by the company Ainol.

USB debugging is already turned on, and I took a look at all of the settings that I could find on it, but the USB debugging bridge refuses to find it.

I figured out that it might be because the tablet ALWAYS connects the USB file transfer (either as mass storage, or media, or camera, but it ALWAYS connects, and I found no option to not connect).

How can I force ADB to find it somehow?
Normally you should have to install the driver of the tablet to have ADB working with it. On the opposite, mass storage usually work out-of-the-box because any PC recognize this standard.

After some search on Google I found some info that may work with your tablet here:
