On an unrelated note, updated the usbnetwork packages according to pnt's suggestions .[/QUOTE]

@NiLuJe sorry about the late reply. Thank you for adopting my idea.

And I have a new idea, which makes easier to switch to usbnet mode without reboot. It's actually borrow from you that reboot kindle app when put "reboot" file into linkfonts/ folder. So I implemented to switch to usbnet mode when detecting "start" file in usbnet/ folder. I put the patch here. If you feel it's good, please merge when next release. Thanks.
