Wanna see something that doesn& #39;t look weird, but turns out to be pretty weird?

So it turns out it& #39;s a USB adapter.
That& #39;s... pretty boring. There were a lot of PCI USB adapters, because right when USB was first taking off, computers either didn& #39;t have USB or only had one or two USB ports.

But wait, why is it using USB-B?

Looking at the board, it& #39;s pretty simple. It& #39;s a single big chip, a small chip, and some support circuitry.

Nothing on the back, either.
And there was no manual or drivers in the box, so I guess we gotta look up those chips to figure out what the heck this thing does.
