[kwlug-disc] Presentation Pointer

Wed Mar 21 18:13:07 EDT 2018

So, I got the laser pointer to work with LibreOffice

I created a file called: /etc/udev/rules.d/80-hs304-pointer.rules

With this in it:

SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="2571",
ATTR{idProduct}=="4101", RUN+="for ID in `xinput | grep HS304 |
/usr/bin/awk '{print $6}' | /bin/sed -e 's/id=//'`; do /usr/bin/xinput
--enable $ID; done"

What this does is:

- Runs xinput, to get a list of devices.
- Select HS304 from it
- Get the 6th field (device ID)
- Execute xinput --enable on that ID

It now works when the dongle is inserted, and flips the slides ...

The dongle does not pair on subsequent inserts, but taking it out and
inserting again clears that issue.
