Forcing Linux to keep charging my Kindle
Linux seems to have weird USB power saving features, my Kindle 3 only gets some charge before Linux powers down the USB port.
When the device is mounted, it doesn't get enough power, with this same hardware under Windows I don't get the message on the Kindle "currently your kindle is not charging." When I eject the device it gets no power at all. I've had a bit of a look around in /proc
A) Ignore: What the f***?
B) How do I turn this crap off?
