In current version of Elantech driver, the hw_version detection is done in elantech_set_properties(), and it's done this way: int ver = (etd->fw_version & 0x0f0000) >> 16; if (etd->fw_version < 0x020030 || etd->fw_version == 0x020600) etd->hw_version = 1; else if (etd->fw_version < 0x150600) etd->hw_version = 2; else if (ver == 5) etd->hw_version = 3; else if (ver == 6) etd->hw_version = 4; else return -1; This "ver" integer really means the version of the IC body, and the magic number 0x150600 is from an old version of our internal driver maintained by Tom Lin <tom_lin@xxxxxxxxxx> (also CCed). Your touchpad seems to be a v3 hardware, but due to the fw_version(0x150500) less then the magic number, it's treated as a v2 by driver. For now, could you please try the below patch? I think I will have to do some history homework and ask our senior firmware guys to come up with a correct patch.
