Why is my device not visable in Adobe digital editions?

I have downloaded ebooks before using Adobe Digital editions using my device Gobii ereader. However when I downloaded ebooks today, opening Adobe digital editions my device is not visable.

While this is an  answer on how to use ADE, it does not solve the problem.

The problem is that although ADE previously recognized a device that has been being sucessfully used, it now refuses to recognize the device.  All suggestions above have been tried, but ADE still not recognizing the device all of a sudden.

This functioned for me, although earlier times it used to function by first opening ADE, then connecting the ereader.

I meant that Reply 24 functioned for me.
