Wemos D1 mini reconnecting all the time to Arduino IDE

 Lately I've acquired some Wemos D1 mini from Amazon and I've noticed an annoying behavior.

Every 2,3 seconds a disconnect and a reconnect sound was produced making impossible any software development on them along with any debugging. 

The problem was a the 3V3 on the CH340C (USB to serial).

After I've added a 100uF capacitor on the 3V3 and not everything is fine again.
