MikroTik

I'm playing around in the RouterOS UI (LtAP Mini), and there's a setting/button called USB power reset.

It's listed as a feature on the MT product page, but what exactly does it do?

AFAIK it disables the USB power for the set number of seconds, then re-enables the USB power.

That's how someone can reset a USB connected device (power off/power on cycle).
