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.

A mouse connected to an usb-port works until some time. Then this device is turned off and never turned on again. I tried to turn off power saving for such devices, but without success. This started with kernels 5.4.0-49-generic and later. I do not see this with kernel 5.4.0-48-generic. This bug renders all usb-ports used unusable. You can unplug the device (a mouse or keyboard) to an unused usb-port. But this will be switched off then soon too. At some point in future you are out of working ports, because all of them are switched off and never on again.
