How to power on an external hard-drive after powering it off?

When I "safely remove" an external hard-drive from my file-manager (Thunar), the whole hard-drive is powered off and disappears from /dev. Therefore, I guess that under the hood, this is done by calling udisksctl power-off -b /dev/sdX which has the same effect.



I thought it should somehow be possible to bring the device up again. After having read https://stackoverflow.com/a/12675749, I thought that powering off is maybe done by writing to /sys/bus/usb/devices/usbX/power/control, but the sysfs seems to remain untouched.



So, how is it possible to power-on an external device again after powering it off with udisksctl? To me, it is annoying that I can not re-mount a partition after unmounting it from the file manager.






mount external-hdd udisks

          Accessing regular linux commands in Huawei's Dopra Linux

          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
