So basically, whenever I plug in my microphone, it doesn't turn on and says "Power surge on the USB port. Unknown USB Device needs more power than the port can supply". This is the first time it has happened but I have had the mic for months. If you need to know, it is a Blue Yeti Mic, here's the link to it on Amazon. https://www.amazon.com/Blue-Yeti-USB-Microphone-Blackout/dp/B00N1YPXW2/ref=sr_1_3?gclid=Cj0KCQjwzunmBRDsARIsAGrt4mtjEfigSRY9I3NUlHNW959Kd_s_5bfDiyYgpxjd5vxa1uZz9aqM73caAg1kEALw_wcB&hvadid=177218034405&hvdev=c&hvlocphy=9014901&hvnetw=g&hvpos=1t1&hvqmt=e&hvrand=17775906225930123621&hvtargid=kwd-14664349409&hydadcr=18911_9698412&keywords=blue+yeti+microphone&qid=1557865395&s=gateway&sr=8-3
