I have a late 2011 MBP which has 2 USB 2.0 ports, 1 thunderbolt/displayport, and 1 firewire 800 port. Thunderbolt is the best connection for running external apps (like running windows externally) I don't have USB3, and thunderbolt still hasn't become mainstream enough for affordable products. there are only a couple thunderbolt to usb 3 adapters and they all seem to have mostly negative reviews and are $80 minimum. I'm not an electronics expert, but i'm curious if anyone thinks it would be possible, or would have advice on resources for learning what it would take for me to BUILD a thunderbolt to USB3 or USB-C adapter. I realize this may not be possible for an individual. Also, I am not a programmer, so building a driver would be difficult, though most likely necessary.
