getting Osys Tablet PC 4 as diver in ADB ?

Hey,

I have got a Odys Tablet PC 4. It's a rocketdev device.
To get root was not so difficult cause, the system images can get by the .manufacturer and normaly mounted for editing fieles in a linux.

But now i wish to use adb for backups and development.

I have tryed to add my Hardware-ID in the android_winusb.inf, but adb can not find my tablet.

Know you any other way to make it working.
