In the UK, due to cultural norms there is a slightly different standard for device connectivity known as "Universal Serial Double-Decker Bus" (USDDB).
@ipg There actually is something that looks kind of like this that’s a standard(ish) for use in Point of Sale systems called “PoweredUSB”!
@xanarin @ipg Dell also used a similar thing once for their laptop DVD drives (apologies for the crap quality)
