@streakmachine To extend the connectivity of my MacBook Air, I bought a Belkin Thunderbolt Dock several years ago. I managed to use every port under testing. The MBA's Thunderbolt port connected the device. I added external USB 2, USB 3, Thunderbolt & FW800 external drives, speakers to the audio out & a mic to the audio in. I connected the MBA to the internet via the dock's Gigabit Ethernet port. This left one USB 3 port unused, so I connected a 20-inch monitor via DisplayLink.
Oddly, despite a massive 6A, 12 volt DC power brick, the dock's USB 3 ports can't pass enough current to charge an iPad or drive the Apple USB Superdrive. But the two USB 2 ports on the MBA could do those jobs so they were connected as well.
Very messy, cables & connectors everywhere, but everything worked just fine. This was with the old 2011 MBA.
