Onda v891W on Debian 10 "Buster" with kernel manual compilation

[rlsl]

I would like to thank everyone for the tips and did as discussed here, installed Debian Buster, recompiled the kernel, I'm using version 5.2.8, with silead module active and my "teclast x98 plus II" worked perfectly, with the specific firmware of the link "https://github.com/onitake/gsl-firmware/tree/master/firmware/linux/silead", but in the "onda v891w ch" doesn't work well nor calibrating with xinput-calibrator, with the same kernel of the teclast and the specific firmware it from the link above, with these options file names "gsl3680-onda-v891w.fw gsl3680-onda-v891w-v1.fw mssl1680.fw" all copies from the original because silead ask me for the firmware file name "silead/mssl1680.fw". Does anyone have any ideas to help?

silead/mssl1680.fw is only requested when the driver can't recognize the system and defaults to a generic firmware name.

Did you create a DMI match for your Onda device, as described here?
