sh: echo: I/O error running dkms-add.sh

[pabloab]

At the end of dkms-add.sh I get a sh: echo: I/O error. The problem seems to be on dev-attach.sh, DEV_NO is empty because there is no "on i2c-FTE100" on dmesg output. Either way sudo sh -c return sh: echo: I/O error. Maybe the way would echo $DEV_NO | sudo tee .... With that change I get a an expected No such device.

I have an Ubuntu 16.04.2 on Asus UX303UB with 64 bit kernel v4.4.0-70. My FocalTech touchpad was working fine some time ago (I usually use an external mouse). Probably stop working on a kernel upgrade.

$ dmesg | grep -E "FocalTech|8042|FLT"

$ dkms status

Other things I tried:

• Touchpad is there: sudo evtest /dev/input/grep -iA4 "touchpad" /proc/bus/input/devices | grep "^H" | grep -o "event[0-9]\+"
• i8042.reset and i8042.noloop=1 on grub options without luck.
• Works again and shows on xinput with sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps && sleep 1 && xinput list but without multitouch.

@pabloab This driver is for Asus I2C TouchPad. You have different device: FocalTech PS/2 TouchPad.

@pabloab I see "PS/2" all over the place. This driver was written for i2c. If your touchpad wants to communicate via PS/2 you wont find a solution here.

Oops! I found some places (mostly bug reports on launchpad) with almost similar machines pointing here as The solution. Sorry to bother. Please close the issue.
