Port reset or port cycling with our hubs can be accomplished by issuing software commands via these methods:. Unlike consumer-grade or industrial USB hubs, where all ports are enabled at power-on, Acroname hubs are able to save customized default settings for each port. As an example, it may be useful in some environments to have all ports default to disabled, so they can be selectively enabled; or default to ports 2 and 6 being enabled and all other ports disabled.

Acroname programmable hubs with software control allow unprecedented levels of flexibility and customization that standard off-the-shelf USB hubs cannot provide. No matter the number of ports or devices you need control of, Acroname hubs are up to the task. Since Acroname hubs are individually serialized, multiple hubs can be present in the same system with individual control of each port on each hub.

Since this is in a lab environment, using custom hardware will require a uphill battle. The hub will briefly disable power output to all 4 of its USB ports, and then enable it again.
