Charging problem with Sansa E250

(1/3) > >>

AstroBoy:
When I use a USB charger and the OF, my Sansa charges.
With RockBox it plays just fine, but gets almost no charge.
The charger is not a computer, just a powerpack.
The chager does charge a Zune and a Blackberry, so I know it is good.

I assume that RockBox only goes to 500MA mode when it sees a computer.
The other devices go to 500MA mode when no computer is found.

Any chance RockBox could be changed to work with a USB charger?

Thanks.

MarcGuay:
Rockbox charging for the Sansas is still a work in progress.  I've never had it pull a noticable charge so I stick to the original firmware.

Here's the task:

What about this?  Seems like it should be working.

2007-11-23 New USB stack with limited capability. Currently it only requests full charging power. Ignore driver popups from Windows.

Did this feature skip the Sansa e2xx?

Llorean:
That means it requests full charging power from the host computer. What it *doesn't* do on the e200 is actually provide that power to the battery for charging.

lol That really made me laugh.  Any chance all that extra power could be put to use?
