Microsoft Sculpt Ergonomic Wireless Keyboard and Mouse + USB Doggle in box BUT I CANT GET IT TO WORK. It has the original plastic on the keyboard I put new batteries in ( not included) and put the USB plug in windows 7 , 8 and 10 computers and it is not detected. The economic mouse lights up as does the light on the key pad but the computers don’t detect these. Maybe you know how to trouble shoot this? Great comfortable keyboard and mouse. As is, no returned.
