Maybe at the moment, but isn't the complex OTG protocol a software question? And again the issue "5V power" I realy would like to see (switchable) power on the USB port, even when it serve some power, less then the standard like 50mA (to power up one keyboard or one USB flash memory device). A powerinjetor with a 9V battery weights >70g. This is not only unsmart to carry it with you, hanging at the Neo1973 (e.g. in a train, hanging up the Neo at the seat in front of you) it creates one problem: it gives a mechanical moment on the device what could - damage the Neos usb jack - rotate your hanging Neo1973 So full power of MObilKOmmunikation on the road, is IMHO only possible with an powered USB port. And again¹ I would love to see a normal USB-A jack (powered) inside a Neo so that I could use USB gadgets on the road without any adapter - the volume of a normal USB jack would be well spend - this normal USB-A jack could be additional to the USB-mini jack inside the Neo. Greetings, rob ¹http://lists.openmoko.org/pipermail/community/2006-November/000000.html When the hardwaredesign is not finished - IMHO would be great to have a (Typ A "DIN IEC 61076-3-107") female connector on the device without the need for an external adapter that can be lost.... ;)
