XPS8940 Logitech Unifying USB receiver cannot be detected

Your screenshot says "driver unavailable"  Did you install Logitiech's Unifying Software?  How are you pairing the receiver to mouse and keyboard, 2.4 GHz or Bluetooth?

Which USB port are you connecting the receiver to? You should plug it into a rear USB2 port. There are two USB2 ports on the back of XPS 8940, next to the Ethernet port. Try both of them...

Defective receiver...?

@Jon-62 

The Logitech wireless keyboard and mouse I have and other ones I had in the past. I never had to install any drivers or do any pairing. Windows always had the drivers and they were already paired  and every thing always worked fine. You should be able to use without installing anything from Logitech.

What Logitech keyboard and mouse are you using?  Not all cordless Logitech keyboards and mice use a unifying receiver.  E.g., my cordless Logitech MK330 keyboard and mouse don't use a unifying receiver, so they are not detected by the software.  The receiver, keyboard and mouse all need to have the orange asterisk symbol on to work together to and be detected by the Logitech Unifying software.

Also, a Logitech Unifying device can only be connected to one Unifying receiver at a time.  If a device is paired with one Unifying receiver, it cannot be connected to another one.

Hi, thanks for the reply. 

Yes, my keyboard and mouse are working perfectly, but only the software cannot detect this unifying receiver. 

The only reason I need this Options software is that I need to customize some shortcut keys on the keyboard. This is only can be done by using this Logitech "management" software/ 

Hi, thanks for the reply. 

I'm using MX Keys and MX330. As said in the post, both the keyboard and mouse are working perfectly, only the software cannot detect this unifying receiver. 

I can use this receiver and both keyboard and mouse on my mac, and mac Logitech options are able to detect and manage it. 

Hi, thanks for the reply. Yes, there's a Logitech software screenshot attached in the post. I tried all the USB ports on the back. 

My keyboard and mouse are working perfectly, but only the software cannot detect this unifying receiver. 

@futandrew , the reason Logitech Unifying Software couldn't detect the receiver because your receiver is not a Unifying receiver.  Get a Unifying receiver and your problem solve. 

Connectivity

• Connection Type: 2.4 GHz wireless connection
• Wireless range: 393.7 in (10m)
• Unifying-ready mouse: Yes
• Unifying-ready receiver: No

Have you followed the advice here ?

Thanks for the reply. 

I read through the whole article, but it is not the issue I'm facing. I tried the software is recommended anyways. Unfortunately, no, this issue is persistent. 

Hi, thanks for the reply. 

As mentioned in the original post, I am pretty sure the receiver is a Unifying receiver. I can use this same receiver on my mac with the same software Logitech Options. This receiver and the software can work perfectly on my Mac Windows system as well. 

After consulting with Logitech technical support team, they have the following statement "If the receiver and the software can work on both macOS and Windows on my mac computer, then the hardware and both keyboard and mouse are fine, there are no hardware issues." Which is a tenable statement. 

So my guess is some adaptation that Dell didn't do well, or there's anything else I should do, but not. 

@futandrew , Someone has the same issue and discovered that there are two versions of MK330.  One without unifying receiver.  You should be able to verify if your receiver has an orange star logo.

Does your receiver look like this

Logitech Unifying Receiver

with the orange asterisk symbol.  If there isn't an orange asterisk symbol, and a similar one on the keyboard and mouse, then you're not using a Logitech Unifying Receiver.  The Logitech MX Keys keyboard is available in a Bluetooth version.
