I have tried recording startup and shutdown now by recording with the command "sleep 10" and doing the manual operation (plugging/unplugging USB) during the sleep delay. Unfortunately, it does not work.

For unplugging I did

sudo umockdev-record --ioctl=/dev/bus/usb/002/009=deskjet-2540-ioctl-shutdown.log sleep 10

and unplugged the USB plug right after pressing Enter. After waiting for the command to exit I did not get a deskjet-2540-ioctl-shutdown.log file.

For plugging I did

sudo umockdev-record --ioctl=/dev/bus/usb/002/010=deskjet-2540-ioctl-startup.log sleep 10

with the intention to plug the printer right after issuing the command.

Note that after repugging the printer will appear under Bus:Device 002:010 so I used /dev/bus/usb/002/010. As the printer is still unplugged when issuing the command there is not yet a /dev/bus/usb/002/010 file and the program exists immediately complaining because of that and does not run "sleep 10".

So any help to record start-up and shutdown of a USB device is appreciated.
