I use Ubuntu 20.04 LTS and a CANON DR-M160 scanner.
When I first start my notebook an Inspiron 15 5000 series and start the Document Scanner app it finds the scanner and all works fine.
Here is some information

ff@ff:~$ scanimage -L
device `canon_dr:libusb:001:007' is a CANON DR-M160 scanner
ff@ff:~$ scanimage -V
scanimage (sane-backends) 1.0.32; backend version 1.0.32
Everything is fine until the scanner goes to sleep after 10 minutes of inactivity. After that, the scanner tries to wake up from sleep mode but does not work.
Here information after the scanner goes to sleep:

ff@ff:~$ scanimage -L
No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).
When the scanner goes into sleep mode, the indicator starts blinking.
The indicator lights up when the command scanimage -L is executed, but after finishing scanner is not available.
Already tried the following without any result:
- Create and enable rc.local service with next code:
#!/bin/sh -e
chmod -R a+w /dev/bus/usb
exit 0
now I have these rules

- Add the following rules to
/etc/udev/rules.d/canon_dr-m160.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="1083", MODE="0777"
SUBSYSTEM=="usb_device", ATTRS{idVendor}=="1083", MODE="0777"
ATTRS{manufacturer}=="CANON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRS{idVendor}=="1083", ATTRS{idProduct}=="*", MODE="0777"
- Tried disable autosuspend usb
sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="/&usbcore.autosuspend=-1 /' /etc/default/grub
update-grub
systemctl reboot
sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="/&usbcore.autosuspend_delay_ms=-1 /' /etc/default/grub
update-grub
systemctl reboot

Update 31.10.2022
Was found same issue on sane side
Perhaps the problem is solved by installing a new version of the sane-backends 1.1.1 library.
Not clear how to install the new version of the library on ubuntu 20.04
Update 02.11.2022
I tried from source to build sane-backends 1.1.1 for Ubuntu 20.04. The problem has not been resolved. After that I formated HDD and install Ubuntu 22.04. The sane-backends library installed the latest version automatically, but the result is the same. Scanner still cannot wake up correctly from his sleep mode
I created new issues on Sane backend. Hope this helps solve the problem
