Adb Not Working

I have soft brick tablet wonder media wm8980
I still can enter it to fastboot mode
My PC win 7 reqognized it as android adb interface ( this mean that driver is installing correctly )
when I type : " adb devices " , why adb just show : " List of device attached " ?
adt-bundle-windows-x86-20140624 and SDK manager was installed correctly
Do I missed some thing or what to do to make adb can communicate with the tablet ?
Thanks for any reply
