AFAIK the cable is a simple USB host to mini-USB device "connect to PC" one like with any camera. Neo will be in device mode with this cable. Charger has a fixed cable and R is inside mini-USB jack, i guess. Charging with the special jr-Y-cable for external powered host mode, with it's 2 pulldown R and ID-R will work. Just connect any USB charger to it. Alas this cable probably will not be included with Freerunner, you have to DIY. /jOERG _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
