I think we need a model number. best guess I have is its some proprietary connector like htcs extUSB that works with an mhl adapter. but that's a wild guess... maybe I'm missing something obvious
Hi unskol, thanks for your interest, unfortunately i have little information as far as model is concerned (I have searched for it). Item was purchased on eBay a year and a half ago (and it still works great) the seller has since stopped trading (or answering emails) and the item is a generic one that I suspect is re branded by who ever chooses to sell it.
Below is what I have as far as model goes,
