The bug is still here in 5.12.13 with asaus m-rbb93 logitech b370 mouse.
After some time (unpredictable, can be few hours or few minutes) mouse
pointer stops responding, though mouse appears conneceted in the
bluetoothctl.

journalctl and dmesg is silent when the mouse stops responding. Is there
any other way to debug this?
When mouse is first connected, dmesg has the message mentioned as the topic of
this bug:

Is there a way to enable this system-wide without patching a kernel, for
a quick test?
I tried to add btusb.enable_autosuspend=n kernel paremeter:
# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.12.13-1-default
root=UUID=ece1a448-6944-4f34-a61c-1742fde2ac3c splash=silent psi=1
nvidia-drm.modeset=1 btusb.enable_autosuspend=n quiet mitigations=auto
# systool -v -m btusb
Module = "btusb"
Attributes:
coresize = "69632"
initsize = "0"
initstate = "live"
refcnt = "0"
srcversion = "8EADE2557C147180496F74C"
taint = ""
uevent = <store method only>
version = "0.8"
Parameters:
disable_scofix = "N"
enable_autosuspend = "N"
force_scofix = "N"
reset = "Y"
But this does not resolve the bug
