A:AnswerThe USB receiver does come with the keyboard/mouse combo. This USB part is hidden in the flap of the box. I almost took the keyboard/mouse back to Best Buy because I thought they forgot the part when packaging. I even checked the mouse where there is a place for the USB plug to be stored. When I didn't see it where I expected, I though they messed up. CHECK THE FLAP OF THE BOX.
A:AnswerHello Kat, unfortunately, you won't be able to connect the MK270 to multiple computers. The MK270 can only connect to one device at a time with the provided usb dongle. However, if you're looking for a mouse and keyboard combo to work with more than one computer, we recommend looking into our MK850 combo. I'll attach a link at the end of this message so you can check it out. It can connect to a device via USB and also via Bluetooth. All you'll need to do is hit a button to switch between the two laptops. It's fast and easy to use, have a great day. https://www.bestbuy.com/site/logitech-mk850-performance-wireless-keyboard-and-optical-mouse-black/5761911.p?skuId=5761911
