Kb7urx - you are for sure a lot more knowledgeable than me. What is a stock adapter and how do I turn it off? I still have the N3 and will try it again if I know how to do that. All I can tell you is that the N3 powers on when plugged into either USB port, but there is no data transmission. (The power light will blink when data is being transmitted, but it stays solid).
I have been in contact with one of the Rokland executives, and here is an excerpt from one of our recent communications that may be of interest to this forum.
"Development for this platform is a lot different then development for
platforms 10 years ago. With Windows you could write one driver and it would more or less work on all Windows computers until the next version of Windows came out. With Android, device manufacturers can restrict what software can be installed, can cause drivers to quit working after updates, and can even limit power output over the USB port by coding. We had looked into iPad driver development and when iOS 4.3 came out, a software change cut USB output over the camera connection port from 100mW to 20mW. 100mW was never strong enough for our product anyway, but some keyboard companies that advertised their product as iPad compatible suddenly found out that was no longer so. Varying USB output among Android tablets is also a concern, as low power may not mean the product won't work, but it may have a much lower signal compared to using on another tablet with higher power output over USB.
And unlike iPad, with Android we are dealing with many device makers with
varying software and hardware differences. You have a wealth of various
generics, and then major brand names. Even the Barnes and Noble Nooks runs Android, but it is a very different device than the Flytouch or Viewsonic Android tablets."
