That'll do it. You've completely drained the battery. Do NOT leave it connected to your computer overnight. Your computer goes into standby or sleep mode & your reader battery will not charge. In fact, it'll actually drain it.
If you want to get your reader working, plug it into the wall with the AC charger. If you have a smartphone take a look at the charger for it. Does it use the micro USB, if so, use that to charge the reader. It will need to stay plugged into the wall for several hours to bring up a charge and then to complete the charge. You've drained it completely. That's why you can't do anything with it.
