Logitech Unifying Receiver USB Dongle - Compatible with M185 Wireless Mouse & Keyboard | Plug & Play for PC, Laptop, Mac | Home Office & Gaming Accessory

This Logitech "Unifying" USB dongle for Logitech wireless keyboards and mice is sold by Fox Deals in San Jose, California. It was packaged in an unmarked plastic bag so I don't know where it was manufactured. The product advertising and invoice state that it is a new dongle, but there is no way of verifying that. As far as I know, a Logitech Unifying receiver (marked with an orange star logo) such as this one can connect to any Logitech Unifying device which is also marked with an orange star logo. So look on the back of your keyboard or mouse, if you see the orange star logo, then this receiver should work. (Note that this receiver will NOT work with Logitech Harmony (infrared) devices or Logitech Nano wireless devices.) The concept of the Logitech Unifying receivers, which operate in the 2.4 GHz radio band, is similar to (but not compatible with) Bluetooth devices. Up to six wireless Unifying devices can connect (be paired with) a single Unifying receiver. If you buy a Unifying device that is packaged with the dongle then the two will already be paired and you can simply plug it in and the device will work. However, if you are replacing a lost or damaged receiver, then you will need to download software to "pair" it with your Unifying devices. Accordingly, since this receiver is being sold individually, then you will have to install software on your computer to get it working. Pairing software for Windows and Mac OS X can be downloaded from the Logitech website. For those of you like me who use Linux, you will need to install Solaar. There is a PPA for Ubuntu and Linux Mint and, as of this writing, packages for Debian, Gentoo, OpenSUSE, and Arch Linux on the Solaar website. In addition, Solaar will also work with some of the Logitech Nano receivers. Anyway, I installed Solaar, plugged in the receiver, and paired my mouse and keyboard. It works like a charm...five stars.
