Hello, I have a problem getting my Elantech touchpad to work with the mainline kernels, and I need some assistance with the code to resolve the problem. The kernels that have tried are 5.9.11 and 5.11.11. With boot parameters i8042.notimeout i8042.nomux, the touchpad is detected but does not work. There is absolutely no response from it with any hid modules loaded. It is reported and seen working on a Lubuntu distro (bionic kernel) when inserting the i2c_hid module. The insertion of the i2c_hid module pulls in the hid_multitouch module when it works, no boot parameters necessary. In the case where it does not work, insering the i2c_hid module does not pull in the hid_multitouch module. I have the bionic kernel code, but I have not as of yet been able to detect what makes it work in contrast to the kernel.org kernels. This I think should lead to a kernel patch. TIA, Hans Schultz
