USB devices stop working after a while

You need to provide the inxi listout (https://forum.manjaro.org/t/howto-provide-system-information/), i.e. you need to see if your drivers are loaded and which. You can also check the lsmod | grep -i "logi" (similar for Chico…, if you can’t find any list it all and check manually, it’s not long). Once you find the driver you can use sudo modprobe to remove and load the driver (man modprobe) and debug it (watch journalctl while doing that). If udevadm monitor (try w/o sudo but I doubt it’s that) doesn’t report anything that points to drivers, low-level issue of some sort (or h/w) I’d say.
