I have a nexus 7 with the QI charging station and also a OTG cable. I use stickmount for my OTG device and all woks great. Now I completly understand that an OTG cable shorts the ground to pin 5 of the usb to tell the tablet its in OTG mode. As a result with the stock nexus you can not charge on that cable. Even though it actually does, the OS is not aware. It would seem the nexus is also blocking the wireless charging. I know I can mod my nexus with custom firmware but I'm not really interested in that. Anyone know if this is defeatable from software? I'm am rooted.
