As long as they are using a wacom serial digitizer which follows the documentation, then the digitizer will work pre-boot.
Thank you for the reply
We wanted to know if tablets have to meet all the requirements given to get full support.
Or if tablets use IRQ5 for only 0x238, or if tablets use IRQ4 for 0x220、0x338、0x300,
then does that mean they meet EEPC support requirements?
