Kernel will respond with the message "Failed to read extended capability bits" just before the psm0 device information string. New manual for Synaptics interface, http://www.synaptics.com/sites/default/files/511-000275-01_RevB.pdf is also helpful to understand what is going on. >Fix: I had patched psm.c, http://codelabs.ru/fbsd/patches/psm/support-synaptics-firmware-7.5.diff I had tested it briefly on my laptop and no regressions were found yet. >Release-Note: >Audit-Trail: >Unformatted:
