Raspberry Pi and USB!
Note: Although USB supports video devices, the USB 2.0 bandwidth is not fast enough for a USB SVGA video capture device to make sense. Not unless the video stream is compressed.
You were wondering. Why do you have to supply power to an Ethernet switch? Why can’t it just get it from all of the connected computers? The reason why this is is due to the standardization of Ethernet. Ethernet standardizes electrical isolation; thus, the switch needs to have its own power source. USB, on the other hand, standardizes a common ground.

Oh, and how do you boot a Raspberry Pi for the first time? You need to boot from an SD card. What about a USB memory stick? Would that work? Only if the USB hub is working.

Be careful of DMA devices. With all of the new hardware being manufactured these days, and all of the multitasking happening in computers, we now have to be weary of new attacks from untrusted hardware.

Wireless USB! Like you were saying, continued extensions of USB. But, security is of issue.

No, here’s the real issue. The real issue is that there are fundamentally two different kinds of networks: ones where information can only reach targeted recipients, and ones where information is only broadcasted. Because of the nature of the underlying network, one communication mechanism may need to be emulated using another.
Finally, what are the pin-outs on telephone cables? What about parallel ports? I need to know what I’m heading into before I try buying the relevant USB adapters.

Look, let’s put additional adapters on hold for now. For now, let’s wait until we can actually test the devices we’ve placed the order for before moving any further.
