Kindle DX USB not working
I have kindle DX B009, version 3.3 and I was always connected a usb to the computer and was able to transfer book via direct drive or calibre.
Last time I check was yesterday and the computer doesn't see the kindle anymore and the kindle doesn't switch to usb mode.
I hear the sound from the computer that a device is attached but I cannot find anything under device manager.
I have also a kindle oasis, connecting it to the same computer works fine.
any ideas how to resolve this?
