thanks for your reply. The Kobo Aura is the newest in the line of Kobo e-readers (the Touch, Glo are earlier versions). I am using Windows 8. When I connect the device with its USB to my computer, it does not show up in Computers, C or E Drives etc. I have replaced the Kobo USB cable with a new Kobo USB to make sure it isn’t that, and it still doesn’t show up. I’ve tried it in another USB port. I still haven’t tried it on another computer. It looks like either a cable problem or a windows software problem... I have downoaded purchased books onto it from Kobo, however I suspect they may have downloaded just thru the wifi connection. I plan on replacing the device today since it’s under warranty. I’ll try the replacement and see if it shows up on the computer, and if so will try your recommended steps to follow...
Greatly appreciated your help...
