I have disabled USB ports via USB and now its absolutely impossible to re-enable them.
The keyboard integrated in the cover is not detected, so it is impossible to lauch the BIOS settings, because the tablet opens a 3×2 grid menu in which the bios setup is on the right. Using the Vol+ and Vol- I can move up and down in this menu, but it is impossible to move right, so, impossible to access the BIOS settings to re-enable the USB ports.
In this picture you can see the pre BIOS setup menu:

I have tried all of these things that I have documented (in Spanish):

Is there any way to load Bios default values?
Is there any way to reset Bios?
Is there any jumper which does it?
The tablet is fully working, so I can start Windows and Android normally, and the touch screen perfectly works. Only the keyboard is not working, of course, neither an external USB keyboard works.
I have also tried to connect a USB OTG keyboard, and it does not work.
Please, I need help in solving this problem.
Thanks in advance
