Hello,

Adding a udev rule is done like this:
- Create a file in the directory where udev picks up custom rules (must be done
as root). Example:
$ sudo nano /etc/udev/rules.d/50-edtracker.rules
- Write the rule line in the file (the id numbers match your dmesg log):
KERNEL=="event*", ATTRS{idVendor}=="16d0", ATTRS{idProduct}=="0aea",
MODE:="666"
- Save and reboot;

I'm not familiar with fedora toolbox but there is some explanation on how to
share the udev rules between toolbox and host there:

The permission issue is not related to Wine but any program who use the input
event interface, as you can read there:

It depends on the driver of the device. I think they consider it a pointing
device, like a touchpad, rather than a controller. Or it's a bug in the driver,
I don't know.

The js interface has been declared obsolete and will eventually be removed from
the Linux kernel itself.

It would give me more time to work on a solution to the off-center calibration
problem.
