FreeBSD is installed on Lenovo Ideapad 320-15AST. Based on several web hits, this model contains the Elantech touchad. There is hw.psm.elantech_support=1 in /boot/loader.conf. This is supposed to make the psm(4) driver to pick it up and create /dev/psm0, but this doesn't happen, and there is no /dev/psm* device. How to troubleshoot this? Yuri
