• Install prerequisites (e.g. Debian packages: dkms and linux-headers-amd64)
• sudo make dkms-install
• sudo modprobe ithc (or reboot)
• Check dmesg for ithc messages/errors.

• Install prerequisites (e.g. Debian packages: build-essential and linux-headers-amd64)
• make && sudo make install
• sudo modprobe ithc (or reboot)
• Check dmesg for ithc messages/errors.

If you get an error in dmesg saying "Blocked an interrupt request due to source-id verification failure", you will need to add the kernel parameter intremap=nosid and reboot. If you're using GRUB, you can do this with sudo make set-nosid. Alternatively, use the driver in polling mode by setting the poll module parameter (e.g. by running echo options ithc poll | sudo tee /etc/modprobe.d/ithc-poll.conf and reloading the module or rebooting).

The driver works in single-touch mode by default. Multitouch and pen data is made available to userspace through /dev/ithc and the HID subsystem. To enable multitouch functionality, you will need to install iptsd.

To enable debug logging use the module parameter dyndbg=+pflmt.
