Hi @JudaRails! Thanks for the diff!! It really worked the compilation here in debian 11 bulleye with linux kernel 5.10.9. Although, it's still not working when I run the fltest.

I made the sudo insmod fl2000.ko to install the module into the kernel and then, I cwd-ed to the directory samples. Compiled main.c to fltest (using make) and the tests failed (probably because it's trying to use modules from arm and I'm not using arm cpu). After that, I ran sudo ./fltest 0 and didn't worked. I also tried sudo ./fltest 0 1920 1080 and it just disconnected all of my usb drivers (I had to restart the system to use it again).

The output of sudo ./fltest 0 is:

I met as like as two peas, hoping to solve it and look forward to it!

very noob here.. how do you apply the diff file please?? it would be nice to get this going. I haven't dealt with compiling in years and was a noob then. any help would be appreciated.
