And indeed when I do a little bit of searching I can see that it’s easy to download a Linux driver for this hub. It is Linux-friendly, in other words. So I suspect that what Peter did was set up a Linux-based system to manage his security cameras and perform automated backups and so on. And when he bought that hub, he junked the Windows-based software that shipped with it and reconfigured it to work directly under his Linux environment."
