Your own research has probably led you to this same conclusion, but to clarify, it is a USB port (although proprietary, even device-type specific; in this case, widely-used in the digital camera industry).
My guess would be that a 'cartel' of camera manufacturers got together at some point, and agreed to make a non-standard plug layout 'standard' across the industry.....in order to keep the purchase and addition of camera peripherals 'in-house'.
It appears that cables for these things are available for purchase, certainly, but they're awkward to track down.....and, as you've also discovered, not all sellers ship to all locations.
Just my tuppence-worth.
