Logitech C-U0007 Unifying Receiver for Mouse and Keyboard Works with Any Logitech Product that Display the Unifying Logo (Orange Star, Connects up to 6 Devices) (C-U0007)

An update on this device, I contacted Logitech support and had a hard time finding this device on their web site. In frustration I logged a warranty case. I was contacted the next day by email and a technician worked with me to isolate the problem. They ended up sending me a new one and I tried pairing it with my 2017 vintage HP laptop and that one would not pair with the mouse either. I then tried pairing it on my new HP laptop using the exact same process and it paired immediately. (The previous USB receiver would not pair on my new laptop). So my solution was to use my old Logitech Unifying receiver that worked on my old laptop and utilized it on that one and used the new USB receiver on my new one. Still don't know what was going on but finally got a resolution. BTW, Logitech Customer Support was excellent and I would suggest if you have a similar issue, just go right to warranty support and forget trying to find the device on the web site.

Worked well - note I think you need Windows or Mac to pair. I has a kb400 kb-400 keyboard and it did not pair automatically. you need to download software Logitech Unifying Software or LogiOptions+ from Logitech to pair it to your device. Simple to setup. Pairing and setup does not work on Ubuntu/Linux.

To be fair to the vendor and the manufacturer, I only purchased this USB receiver because I already had a K350 keyboard sitting on the shelf. When my old keyboard finally gave up the ghost, I decided to see if the Unifying receiver would connect with my K350. The original receiver got lost during one of our moves a few years ago, so I figured it was worth a shot. I spent a couple of hours trying to unsuccessfully trying to connect the new USB receiver with old K350. I made the necessary upgrade, downloaded and installed the Unifying software, changed batteries, and even multiple restarting the laptop. Try as I might, the old K350 just did not react to the receiver. Because I can not verify it is not just the old K350 keyboard unable to recognize the receiver, I do not see my effort to save a few bucks as a complete waste. My laptop does recognize the USB receiver in settings, but it will not connect with the K350.

Not much to say other than it works. I have a VERY old version of this and needed the same for a new laptop in a different room. Even works well with my also VERY old Logitech K400 keyboard. Great price too.

I somehow misplaced the USB dongle for my Logitech K350 keyboard. Funny because I put a note on the original box which aparently reminds me of where the original actually is, but I can't read my own writing! This replacement worked fine and it will also accept certain models of their wireless mice. Carrying the Unifying certification, I would think it would work with all their USB input products, as well as those of other manufacturer's. It's not mentioned in the instructions but I would be interested in knowing. BTW a warning. Windows 10 update has affected some systems; the keyboards have slow response. You litterally have to hold a key down for some 3-5 seconds before you get a response. I spent time researching this and apparently the most likely cause has to do with the EASE OF ACCESS section of your Control Panel. If you don't use the fully itemized version of Control Panel, select Control Panel and then from the old, normal control panel screen, go up to the file name and click the right arrow or down arrow that follows "Control Panel." If there is no arrow next to the name, just click on the name Control Panel at top and one will appear. Then select All Control Panel Items. You will now see a list of some 25 individual items rather than the old screen which has about six main categories. Now select Ease of Access, then "Make Keyboard Easier to Use." You will find a category regarding Filter Keys. It will read Turn On Filter Keys. If it is checked as being ON, uncheck the box. You don't want the filter keys on because that is the usual problem of having the slow response from the keyboard. Oh, one warning. Hit Apply. I forgot to and wasted another half hour trying to find a solution in the Registry which didn't work. I went back to Ease of Access and found the filters still being checked as ON. After trying three wired keyboards and one wireless without success, this was quite a good feeling!! If this isn't your problem, and you've already replugged in your USB cable, you are probably going to end up in the registry which is a place of last resort. I have no idea how the filter key got turned on but there is a suggestion that it may have to do with a Windows update. This seems to go back to Windows 7, but I have had Windows 10 for more than a year.

1. Please make sure you are 100% sure that this is the correct USB receiver before purchase. 2. The packaging is from Logitech but not manufactured for the US market and all is in Chinese, not English. 3. NO RETURNS are allowed for this product. Otherwise, works well with products it is designed for. Note: I ordered this Unifying USB receiver for a K270 Keyboard. If your keyboard has the Unifying star on it, this should work. If your keyboard does not, it may be a part of a COMBO keyboard and mouse option sold by Logitech. Even though you may see the K270 on the website stating Unifying, it is NOT if it was a combo purchased product. The COMBO uses a non-Unifying USB receiver C-U0010 I hope this helps you to decide correctly if you are replacing a K270 keyboard receiver.

works as advertised

Lost my keyboard receiver when I left it on a remote computer. Ordered this replacement after confirming on the Logitech website that it would work with my K400+ keyboard and trackpad. Received dongle and plugged-in. It did not work right out of the box. I read the very tiny info sheets that came with the receiver to no avail. Finally Googled and went to the Logitech website. For a Mac computer, you can program the receiver via software that you can download. I really wish Logitech had better instructions with the receiver and on their website. But, in the end works great - even at 1/2 the cost of a new keyboard, lol.

Working fine. It did not come in Logitech packing so that seems to be a drawback although it seems to be a genuine product. Had to download a software from logitech website and it immediately recognized my wireless keyboard. Essentially i had to buy this because i seem to have misplaced the wireless receiver for my KBD. Since it support up to 6 devices it might be helpful in avoiding a clutter with other logitech wireless devices I may use.

Works well. Easy to pair.

compatible with Logitech devices that use the Unifying receiver - my MX Master keyboard and MX 2 mouse. NOT the newer Bolt devices. Lets me use my mouse and keyboard on two devices.
