One thing I've noticed: If I have something that's purely power plugged in, it works great. If it's a device plugged in it will turn it off but subsequently turn back on a few seconds later.

Thanks for your report! Regarding auto reconnection, can you try using option -r N, where N is some number, say 10 or even 100. This will try to turn port off many times in succession. Very often this helps to actually turn it off.

One more question: this is USB3 hub, and are apparently using USB2 connection.

Can you please try connecting it to USB3 upstream port using USB3 compliant cable?

[parkerlreed]

Aha yeah didn't realize I wasn't using it in the 3.0 port

Normal power off for the mouse didn't stick and spamming occasionally stuck. -r 100 seems to be more consistent

Oh is the code automatically trying both the 2.0 and 3.0? I setup the for loop because of the comment in the README lol

[parkerlreed]

So yeah the code by itself does do both! Nice. Yeah so the rapid succession turn off works.

Added in fa90f13 - thanks!

Yes, I have implemented automatic handling for USB3 duality just few days ago.

Note that you can avoid using sudo if you configure udev USB permissions. Simply create a file /etc/udev/rules.d/52-usb.rules with following content:

SUBSYSTEM=="usb", ATTR{idVendor}=="05e3", MODE="0666"

and then run this command to reload udev rules (or simply reboot):

sudo udevadm trigger --attr-match=subsystem=usb

After doing this, uhubctl will not require root to work.
