How to conect USB modem dongle to tablet AOC Breeze
I spent a long time trying to UMTS Manager and XDA forum script, but I realized that when the app was active, the script runs fine (the ping give a good request), then I thought the script needed more time to connect so I make a little modifications to the file "system/etc/ppp/peers/conf-chat" replacing all the "TIMEOUT 3" by "TIMEOUT 0". Then in the GScript Mod app I change in the inet-ON script the sleeps in the for statement (that was setting in 3) for sleep by 5.

When I make these little modifications the tablet connects and surf in the internet like a charm!

Please, sorry for my english and for answer my own question in this way but I think could be another guy with the same problem.
