you could ask kobo what is "supposed" to happen, maybe you will get lucky and get a quality response.

I recall another discussion to do with charging, where it said that the way Kobo determines whether it is connected to a PC or to a charging plug is be measuring voltages or current levels on certain USB pins; maybe that is a factor in deternining how "connected" the device is, also ?
I trust you have checked that your device is reporting 3.11 installed ?
That is visible in the attachments I placed (post #275) so yes.
But now I know it is not my device problems by the last post of davidfor:
- Using "Eject eReader 3.11.0" from the "Safely remove device" icon in the system tray will not let the device restart without disconnecting.
- Using "Eject" on the icon in the "Devices and Printer" folder will not let the device restart without disconnecting. (again thanks for clarify) so case closed.

But the charging thing is a bit of "magic" some say when pin 2 and 3 are connected (short cirquit) it is a charger, if not, is is a computer, other states that all above 500 Milli amps are seen as chargers.. but that is not the way a charger works, it only gives what the device ask so if it's charging by a regulator not more as 300 milli amps to prevent that it will blow up your usb ports, it will never been seen as a charger.
it could be a combination, if pin 2 and 3 are short cirquit, then it is a charger and more current can be drawn so the device switch inside to accept a bigger current like my Nexus tablet does when connected to an usb port it takes 400 milli amps but when connected to a charger with the 2 pins shorted, it drawns 1,5 amps, but I had once an usb cable that has internally shorted pin 2 and 3,off course didn't send or receive information but it blew up my HTC phone... and the windows energy scheme can shut down USB ports to save energy and go into sleep...
My Glo and Aura HD accept a old charger,but when I connect my Sony to it, it says "this is not a charger so charging is suspended" (or something like that.. it's on Dutch..)
I saw 3 of 4 explanations on the internet about the charging,and they all where different..
