Why doesn't the battery charge in USB network mode?
Title says it all...
Not that it's terribly important, I'm just curious. 99% of the time I'm having the device connected with USB network on, and it just keeps discharging. Is there any technical reason for this, or is this just some kind of bug (or rather: "non-feature") in the kernel module or whatever else is responsible for the usbnetwork stuff, maybe even the hardware itself? EDIT: Weird. Now it's charging even though it is in network mode. So maybe I'll change the question to: "Why is charging behavior in USB network mode nondeterministic?" ![]() Last edited by ixtab; 07-28-2012 at 06:03 AM. |

My daughter got a new Kindle recently, and battery wouldn't charge fully, needed a software update. Problem might lie with an underpowered USB connection.
Some plug in mulit - usb adaptors do not have sufficient power for charging, so always use one connected to directly to your computer for charging purposes. I assume that your computer can see the programmes in your Kindle. |

I haven't played with my touch much yet, but what does the kernel log says about the charger on the touch? It was pretty verbose on the K3, even on my slightly broken device ;-)

If you want to see the source for your "foofy code", just look in the GPL source code from amazon. Search for "ACCESSORY". |
