That's strange. Could you please do the following?

1. Start "sudo usbhid-dump -es -m 5543:0781 | tee usbhid_coords.txt".
2. Make a horizontal stroke with the pen, starting outside the left border
    of the drawing area, going through and out the right border. Like this:

      `:
     .-~---------------------------.
     |    * * * *                  |
     |  .-----------------------.  |
     |  |                       |  |
     |  |                       |  |
     | --------------------------> |
     |  |                       |  |
     |  |                       |  |
     |  |                       |  |
     |  `-----------------------'  |
     |                             |
     `-----------------------------'

3. Make a vertical stroke, starting outside the top border, going through
    and out the bottom border. Like this:

      `:
     .-~---------------------------.
     |    * * * *   |              |
     |  .---------- | ----------.  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  `---------- | ----------'  |
     |             \|/             |
     `-----------------------------'

4. Stop the command by pressing Ctrl-C.
5. Send me the resulting "usbhid_coords.txt" file.

And then also the following:

1. Make sure you have "xinput" package installing by running
    "sudo apt-get install -y xinput"
2. Find out pen input device ID: execute "xinput list" and remember the
    number after "id=" on the line with your tablet name under "Virtual core
    pointer" group. I.e. NOT under "Virtual core keyboard" group.
3. Start "stdbuf -oL xinput test ID | tee xinput_coords.txt" (replace ID
    with the device ID you discovered in the previous step).
4. Make a horizontal stroke with the pen, starting outside the left border
    of the drawing area, going through and out the right border. Like this:

      `:
     .-~---------------------------.
     |    * * * *                  |
     |  .-----------------------.  |
     |  |                       |  |
     |  |                       |  |
     | --------------------------> |
     |  |                       |  |
     |  |                       |  |
     |  |                       |  |
     |  `-----------------------'  |
     |                             |
     `-----------------------------'

5. Make a vertical stroke, starting outside the top border, going through
    and out the bottom border. Like this:

      `:
     .-~---------------------------.
     |    * * * *   |              |
     |  .---------- | ----------.  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  |           |           |  |
     |  `---------- | ----------'  |
     |             \|/             |
     `-----------------------------'

6. Stop the command by pressing Ctrl-C.
7. Send me the resulting "xinput_coords.txt" file.

Thank you!
