First problem is that these touchpads are dying off (losing their sensitivity and response) when the system is put into pm-suspend and then waken up. Another problem is that on reload (modprobe -r ... && modprobe ...) of psmouse module they are dying off too, in 'dmesg' coming with some weird-numbered indexes (like, input5 on initial load and input292 on reload of psmouse). There are some bugs reported in Ubuntu Launchpad on this topic (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1519034 is my own, also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490130 , https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1506363 , https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1504445 and some others). Also there is a proposed patch at https://marc.info/?l=linux-input&m=144312209020616 and one more report at http://www.spinics.net/lists/linux-input/msg41634.html For me, these problems look related. I have Asus X302LA on which I am testing Ubuntu Xenial and whose touchpad exhibits this problem. If you need I could provide my assistance in testing psmouse module on this hardware. Thank you in advance for your response.
