Description:
|

Changing mode for USB port.
|
|
Writing to this can disable charging.
|
|
|
|
Possible values are:
|
|
"auto" - draw power as appropriate for detected
|
|
power source and battery status.
|
|
"off" - do not draw any power.
|
|
"continuous"
|
|
- activate mode described as "linear" in

This is useful for unstable power sources
|
|
such as bicycle dynamo, but care should
|
|
be taken that battery is not over-charged.
