Why a 1-port powered hub? I'm happily injecting +5V down the USB lines without issue.

Also, since these adapters are quite expensive anyway (£5 each + £5 international delivery!) - a slight cost hike for added functionality shouldn't be too much of an issue in the long run.



If push came to shove and you wanted to disconnect the main supply from the N810 you could use a 2.5mm TRS socket that disconnects the internal supply from the external.


(I know I said Nokia Style connector earlier - I should've said the above!)


You should be able to source small inline 2.5mm TRS sockets quite easily.



Why I'm pushing for this: piggybacking male-female plugs over and over again to achieve one specific solution at a go results in a heavier Frankensteinesque dongle. An all in one elegant solution like this would be best for all concerned. Few devices work on a <100mA supply anyway [some memory card readers, keyboards, self-powered USB devices, and that's about all that spring to mind] - extra power injection is needed in the long run.



Also - while we're on the subject of possible improvements in manufacturing. Would you consider using a 90 degree Micro-B plug. Again - I know you have the 3D swivel for any degrees of freedom - but with a 90 degree right angle plug you'll decrease the amount the plug sticks out of the size much further. Costs in terms of manufacturing should be limited as the plugs themselves are only a few cents more than the normal ones.



My 2 pence, if you're manufacturing these from scratch then we may as well get all the bells and whistles at once!
