Pen not working on Surface Pro 2017

[geoffholden]

After trying the latest 4.14-rc8 kernel, I still have no pen support.

I've added the udev rules for the different devices in the 2017 version:

% diff 99-ipts.rules /etc/udev/rules.d/99-ipts.rules              
17a18,27
> 
> # IPTS Touchscreen (SP2017)
> SUBSYSTEMS=="input", ATTRS{name}=="ipts 1B96:001F", ENV{ID_INPUT_TOUCHSCREEN}="1", SYMLINK+="input/touchscreen"
> 
> # IPTS Touchscreen (SP2017)
> SUBSYSTEMS=="input", ATTRS{name}=="ipts 1B96:001F UNKNOWN", ENV{ID_INPUT_TOUCHSCREEN}="1", SYMLINK+="input/touchscreen"
> 
> # IPTS Pen (SP2017)
> SUBSYSTEMS=="input", ATTRS{name}=="ipts 1B96:001F Pen", SYMLINK+="input/pen"

But evtest still gives me nothing:

Did you try repairing your pen?

[geoffholden]

I've tried, but it doesn't help. /dev/input/event21 is the Bluetooth connection to the pen, and that reports the pen button (eraser end), but nothing else.

[jakeday]

@geoffholden Can you get me the output of lsusb and lspci?

[jakeday]

@geoffholden Nevermind, I figured it out.

[jakeday]

This should be working now with the build and changes I just pushed. You'll need to install the latest kernel and headers, use the new udev rule, and use the appropriate updated ipts_firmware package.

Still no-go on the pen. :( Touchscreen works fine though.
