I found a solution myself.
Edit /etc/laptop-mode/conf.d/runtime-pm.conf
Search this:
# The list of Device IDs that should not use autosuspend. Use system commands or
# look into sysfs to find out the IDs of your devices. # Example: AUTOSUSPEND_DEVID_BLACKLIST="046d:c025 0123:abcd" AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST=""
Then do lsusb and find the mouse:
lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 003: ID 5986:0102 Acer, Inc Crystal Eye Webcam Bus 003 Device 002: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
You find the mouse -> 093a:2510
Now edit AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST="093a:2510"
After next boot, your mouse will not suspended any more.
However, if you wish the mouse to be suspended, but want increase the delay (which is 2s by default and rather short), edit the last line:
# Auto-Suspend timeout in seconds # Number of seconds after which the USB devices should suspend AUTOSUSPEND_TIMEOUT=2
Good luck and thanks for the answers.
Best
