set_vibration lock after 16 uses giving "no space left on device"

[Krayfighter]

the following code works

import inputs
from time import sleep
controller = inputs.devices.gamepads[0]
for i in range(16):
    controller.set_vibration(0, 1, 100)
    sleep(.1)

so long as the range is less than 17

otherwise, is will give the following stack trace

Traceback (most recent call last):
File "", line 1, in
File "/home/aidenk/.local/lib/python3.10/site-packages/inputs.py", line 2983, in set_vibration
self._set_vibration_nix(left_motor, right_motor, duration)
File "/home/aidenk/.local/lib/python3.10/site-packages/inputs.py", line 2969, in _set_vibration_nix
code = self.__get_vibration_code(left_motor, right_motor, duration)
File "/home/aidenk/.local/lib/python3.10/site-packages/inputs.py", line 2963, in __get_vibration_code
buf_conts = ioctl(self._write_device, 1076905344, inner_event)
OSError: [Errno 28] No space left on device

this work inside and outside of a loop, and for the duration of the process' lifetime, limiting the number of calls to this function to 16 for the entire program runtime

I also noticed that if I had 2 python instances open, I could use all the the 16 function calls in the first, and the second would be unable to call the function, giving the same stack trace.

The reason why this is happening is because the set_vibration method actually writes the effect to the gamepad when called. Your gamepad probably has 16 slots for effects. After calling it 16 times, there is no more space to store another effect. This library is unmaintained, but you can address it for yourself by splitting out the writing of the effect into its own method that is called only once.
