Thanks for the files :)

I need help from the pro's in diagnosing what the hell is going on with my charging

So I installed the charger mode control , here is what happen :

1.The original cable + charger were connected to the nook - Spare Parts showed USB charging

2.I enabled "force 1.9a" - still USB charging

3.Disconnected cable at the tip

4.Reconnected cable - AC charging

5.Disconnected -> Reconnected - USB charging again , tried a number of reconnecting and still USB

6.Tried to reproduce AC charging with "force 1.9A" on off - No Luck ( about 20-30 re-connections of the physical cable or even charger from the wall , I stopped because I was afraid it would cause damage )

7.Tried a couple more time to switch "force 1.9A" on and off again - still only shows USB

8.Left it a couple of minutes ( checked the logs )

9.Enabled "force 1.9a" and voila! - again AC charger detected

Now , It's too inconsistent for me to figure out why its happening so I hope you can find out something from my logs that can help

I'm not sure if the app did any effect on this issue and I don't wish to test it more if I don't get any more data out of it...

But , I would be willing to do a more "controlled" test and logs , just let me know what you need

Here is the last log that shows the change ( force 1.9a while charger is identified as USB , disconnecting and reconnecting the cable - identified as AC )

Values at Nook Charge Control :

DCM - 0 ( OFF ) , 1 ( ON )
IUSB - 500mA

Can anyone help me trace the problem?

Is it the charger / cable / software?

Here is another log just for the charges so you can see the frequency
