Freezes mouse pointer

[Arinerron]

Hey! When I run sudo ./ml_manage.sh load, it returns no output, but my mouse pointer disappears until I unplug and re-plug it back in. Then, I execute gcc -o ml_control user-space.c, and again, no output.

I'm on Linux Mint. If you need any info, feel free to comment!

I'm trying to get this driver so that I can fix this bug with a program in Java I'm working on to control the launcher:

Great to see that this project is still of interest to some folks out there!

I wrote the driver 10 years ago as a proof of concept, and am surprised today that the USB interface has remained stable. The driver only makes use of bare USB primitives offered by the kernel. It probably needs a few tweaks here and there to function properly, in particular to the module loading part (to avoid conflicts, such as a freezing USB mouse). Unfortunately, I do not have the cycles to pursue this; such patches would have to come from the community.

Then, I execute gcc -o ml_control user-space.c, and again, no output.

This just compiles the user-space component. What were you expecting?

My tip would be to first debug the C-side, before looking at this through Java.

The reason your mouse freezes, is probably because the load script removes the usbhid module. A fix would be to remove usbhid, insert your module, then insert usbhid again.
