It was enabled by default in the new firmware, although before that I took the same steps as you di ...

Thanks for the reply batojay.  
I accomplished update the android image (I tried to press the power button before connecting the otg cable and it worked) but now has the same problem which i mentioned earlier
Apparently the update does not completely replace the android system and the problem persist.
Of the TTL debug pins i get the following:

I have been reading and apparently it goes into suspend loop.
For now, i must resolve this problem (no idea how) before continuing.
I wait for your comments and i hope you succeed with the adb.

I made it!
This post helped me to stop the suspend loop: http://forum.legato.io/t/suspend ... uspend-to-debug/251
Then, combining the last post for enable adb, and this: https://forum.xda-developers.com/showthread.php?t=893434
I do not why this time dont request me to verify the key and after a reboot all work fine, and automatically opened the vysor and i see the screen.
Finally i won, and i'm so happy that don't know what do now

Hi gtrangoni,

I also experience the console freeze, but dont know what to do , since in the GUI mode using LCD screen all works fine. It is great that you have resolved the problem. I will try your solution when I get the time.

Thanks....

I finally able to use ADB using this command:

1. setprop persist.sys.usb.config "adb"

Congrats batojay! Enjoy it now. Is the beginning for do something more, i guess.
Yes i saw that command. Another useful is "svc" command. With this you can control power, wifi, data and usb.
For example:
svc usb getFunction -> gets list of currently enabled functions on device

Thanks gtrangoni. Well, for starter, I have managed to toggle some io pins on & off from adb terminal if you are interested.

I found solution for unauthorized device in adb:
Copy file from %USERPROFILE%\.android\adbkey.pub to folder /data/misc/adb
Rename file /data/misc/adb/adbkey.pub to adb_keys
This could be done easily by mounting device in mtp mode:

1. svc usb setFunction adb,mtp

Copy code

copying key file into phone storage and in console:

1. cp /mnt/sdcard/adbkey.pub /data/misc/adb/adb_keys

Copy code
