Sebkinne, you statement is confusing. How do I know if I need extra power?
In the brief video on installing the Pineapple for Linux, it shows both connected with no explanation. So it appears the proper configuration is to have both female on the Y-cable plug in.
If the Nano is only being used, is this configuration OVER powering the device? Can you over power the device using the Y-cable (excluding using improper/non-standard USB power rating of course)? Is this the cause of over heating?
