sorry for bringing this up yet again. I am still unsure what kind of usb micro adapter i would need that doesn't involve power injection. what about this one? Description says its a "Micro-A" plug. Yet it looks different than the plug of the n810 adapter you linked (which looks more like a micro-b plug). qouth the wikipedia: excuse my stupidity. I can't make sense of this. n810 plugs look like micro-b, yet it would be logical to use micro-a. Help please!
