Hi, all
On the question of power injector implementation to enable host mode USB OTG on the Nokia 770, has anyone tried running a USB phone charger for phones that weren't designed to be charged by USB out-of-the-box (OTB <.|,>) and plugging in a 9V battery in a casing with a stereo mini-plug port or smaller and the USB end into a USB hub then the hub via a USB A/MtoUSB-mini converter into the Nokia 770 mini USB port. The hub should give a number of free USB A/F ports for plugging in devices minus whatever splicing arrangement one prefers for connecting the charger-turn-injector into the hub. I suspect one would have to chose a hub that allows (against pre-USB-OTG specs) to feed additional power to the host to support host mode functionality. Power adapters in pre-OTG specs are supposed only to feed power to higher-demand devices, not to their host. Also, it would be nice not to be tied to an external wall plug, hence the battery in some web-posted designs makes sense. Another thing to charge, but what's new. Edison won out in devices, Tesla in efficient long-distance power distribution. Home is where you charge your batteries all the OTG devices of your e-life: get one, it's really fun.
Cheers,
Paule
