Restart USB-C command?

[axrusar]

I have an USB-C external SSD flash drive that i am able to use in my laptop.
I am able to plug it on the usb-c port and it works. But if i eject it, and try to plug it again, it will not be read anymore
by the system. I need to restart the computer in order to detect it again.

Here is my system report: Right now the disk is plugged in to my laptop and is not being seen. But if i use a usb-c to usb3 adapter, it works.

If you click Power Off button above you'd need to reinsert cable.

I see..
So in Mint if you ONLY click the eject button on the file manager, the usb-c port freezes rendering it useless until the next restart of the computer.



But i see there is a "Power off disk" button in the disks applet that ejects it properly, then i can use the port for anything else. An extra unnecesary step just to eject a disk IMO

BUG?
What is the point of the Eject button in the file manager then?

If you are asking me, sorry, I was just trying to supply (hopefully) practical workaround to the fellow forum user.
In fact these Nemo buttons are capable to unmount most of partitions and USB pen-drives. Bad luck your device turned out to be nasty.
Buttons are just interface to system commands, and in that department there are several for eject, unmount and power off actions.
Probably the good way to remove some device would be a sequence of two commands

Code: Select all

sudo umount /dev/sdb1
sudo udisksctl power-off -b /dev/sdb

change sdb1 and sdb for real values
