Go into the device manager and delete all the entries for USB devices.  Then restart the system (they'll be redetected).  That should clear the error - but if it comes back with the same fan, have that replaced under warranty.

It shouldn't -- it sounds like the fan you purchased is faulty.

That solved my problem, but when I plug the fan back in, everything repeats again, it stops working and when I install the driver again, it starts to work.

I was thinking about buying a laptop cooler but now I'm not sure about it, can the same thing happen with the cooler pad?

Good to hear that, hope there won't be any problems with it.

Thank you so much for helping!  :)
