In other threads I've mentioned I have a USB-powered external SATA dock, which I'm using mainly as a backup device. Currently, I have a script to power it down by doing this sort of thing: echo 1 > /sys/block/sdd/device/delete I can then turn it on again using: echo "- - -" > /sys/class/scsi_host/host6/scan This works, but is a kludge. A cleaner way would be to use: udisksctl power-off -b /dev/sdd This works too, but unfortunately also removes the /sys/block/sdd files, meaning I can't turn the thing on again. However, if I physically switch it on and off, it reappears, IOW it causes a USB "insertion" event. Is there a way to cause an insertion event without physically doing anything to the dock? poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
