This product is the last crap! Surely it can not simply be that in which a super run, in the other not! I bought me the part, connected, and what happens? NOTHING! The part is a shithole! The LEDs do not light, nevertheless my connected devices are hot, but are not usable, and if you change the port on the PC, the computer crashes! In my opinion, it is an impertinence to bring out such a thing, and I can only advise any of purchasing this product! My mouse is now probably eloped, I can only hope that my other devices have remained intact! Incredibly and irresponsible something!
