I started noticing this today after a reboot (kernel 5.8.0-25 hirsute/dev repos). Both my keyboard and mouse have begun autosuspending after only a few seconds on non-use. Echoing 'on' to the appropriate /sys/bus/usb/devices/usb#/#-#/power/control path gets them working again.
This is a desktop with no laptop tools / power management packages installed. Looks like udev is being too optimistic about what it should shut down.
