xow uses up 20% of my CPU constantly, even if controller is off

[thingsiplay]

I am on Manjaro for a few months now and the issue is still there. xow constantly uses up 20% of my 4 core with hyperthreading CPU system without even having the controller on. It is paired with my wireless dongle from Microsoft and the systemctl service is enabled. Right when I boot up and do nothing, it will start the xow service and just consume 20% constantly even if I don't play. I usually stop the service after booting and only start the service when I want to play a game with gamepad support. But 20% just for the gamepad support is a bit ridiculous and can't be right.

I don't know what information I should provide. I was compiling the source code from this Github page directly and just now tried if installing xow from the AUR would solve the issue. But its the same.

Which libusb version? Could you post a log? journalctl -eu xow.service

Edit: I just read the issue at #141 and understand the problem now (incompatible). I think the current hacky solution would be to downgrade obviously. But I don't know if this is a good idea, because the other components (maybe even more important components) would be incompatible with older version too. Is it safe to downgrade? I use other devices than this controller too, in example backup hard drive which is not connected right now.

The entire log of output from journalctl -eu xow.service:

journalctl -eu xow.service.txt

I didn't play much with the gamepad on this system so far. These usb and libusb related stuff are installed on my system:

$pacman -Ql libusb
local/hidapi 0.10.1-1
    Simple library for communicating with USB and Bluetooth HID devices
local/lib32-libgusb 0.3.6-1
    GObject wrapper for libusb1
local/lib32-libusb 1.0.24-1
    A cross-platform user library to access USB devices (32-bit)
local/libgusb 0.3.6-1
    GObject wrapper for libusb1
local/libusb 1.0.24-2
    Library that provides generic access to USB devices
local/libusb-compat 0.1.7-1
    Library to enable user space application programs to communicate with USB devices
local/libusbmuxd 2.0.2-1
    USB Multiplex Daemon

The gamepad itself works just fine and I played mostly one or two games on Steam with it so far and quick tests with RetroArch worked too. So everything seems to be just fine, besides this constant high CPU usage. xow has one hyperthreading core on 100%.

I should mention, that I was using Ubuntu LTS before switching to Manjaro in January (a few months back) and don't remember such a problem (Edit: But don't want rule it out entirely, maybe I just didn't noticed it). Maybe this is a useful hint. Here is output from lsbusb too:

After reading in the other thread #141 I did the same and downgraded libusb for now with the command sudo pacman -U https://archive.archlinux.org/packages/l/libusb/libusb-1.0.23-3-x86_64.pkg.tar.zst . And added a rule for pacman to ignore this package from being updated in sudo vim /etc/pacman.conf with a line IgnorePkg = libusb . Now I do not get these CPU spikes anymore, but I wonder if this causes any incompatibility with the rest of the system.
