The tool was
USBDeview. With it you can check what is connected and see the drivers installed for each of the devices.
Is the Glo seeing the PC when connected? i.e. Does it prompt to connect? Does the battery charge?
Have you tried a factory reset? You stated that Kobo said to do this, and because of the tone and the "different resets" statements, I read that to mean you had already tried and it didn't help. But, rereading it, I am not sure that you have done one.
