ipod not charging(Win8), does sync.

Hi.

I would like to ask if its possible that the ipod nano's of the 5th gen. are compatible with Windows8.

Recently I installed windows 8 and cannot get my ipod to charge anymore. It works fine on other pc's and on the same one but with windows 7.

The device connects properly. Gets recognized and sync's without any problems. But after syncing is done it stops charging immediatly.

Also the usb port which the ipod is connected to give's a code(21) which says that the device is beining removed. But ofcourse, its not.

Is there anyone who has a solution to this?

Thank you in advance.
