I was able to get the seek app running on my Nexus 7 to the same extent as on my Radxa Rock. It turns out that my micro USB extension cables don't seem work quite right. In any case, I was able to run adb via wifi to my Nexus 7 and here is a logcat capture from about the time I allowed the app to use the USB.
