Logitech G Hub Mouse Not Connected
Plug the receiver into a different USB port on your computer. If possible, don't use a USB hub or other similar device. If you are using a USB 3.0 port try plugging the device into a USB 2.0 port. Try reinstalling the Logitech Connection Utility software and re-pair your device. It should re-enumerate and be detected in G HUB. G HUB should then download the driver for your device. If issues persist: Run G HUB with the default settings: 1. Exit G HUB by right-clicking the applet in the task tray and selecting Quit. Navigate to C:UsersUSERNAMEAppDataLocalLGHUB, where USERNAME will specific to your account. Exit, then re-launch the G Hub app. If it still shows disconnected, unplug and replug mouse. If it still shows disconnected, uninstall and reinstall G-Hub (I had to do this) a. Exit G Hub (obviously) b. Open Finder, go to Applications folder. Delete the Logitech G Hub app (move to trash) c. Re-install G Hub the same way you did before.

I discovered I couldn’t get my G900 Gaming Mouse to work inside Logitech Gaming Software. The message read, “Device not recognized” and only limited features were available. I was instructed by Logitech Technical Support to install G HUB instead of Logitech Gaming Software and now it’s working. According to tech support, Logitech Gaming Software is no longer supported and requires the latest version of G HUB. I wrote about this issue under my G900 review because the documentation and support website needs to be updated.
Here are the steps to fix G900 Wireless Gaming Mouse “Device not recognized”
1. Uninstall Logitech Gaming Software since it’s no longer supported. Note, if you have an older G900 and were instructed to use the Logitech Gaming Software then stick with what you were told. Otherwise, continue with the steps below.
After uninstalling Logitech Gaming Software I just skipped to step 2 and it worked. But, if you have trouble you can try using the steps 1a through 1c before moving to step 2. I’ve actually done this both ways.
1a. Go to Device Manager and choose Mice and Other Pointing Devices and look for the mouse drivers and uninstall them.
In my case, I only saw several instances of HID Compatible Mouse and I deleted those and then unplugged the G900. I had a second mouse handy so that when I deleted all the HID’s [one HID was the G900], I then plugged in the second mouse so that I could actually still navigate on my computer for step 1b. This repopulated the HID but did not interfere with the process since the HID was for the second mouse and not the G900.
1b. Restart your computer.
1c. Plug your G900 mouse back in.

2. Assuming Logitech Gaming Software is uninstalled you will need to then download and install G HUB. This is found if you scroll down on the G900 Chaos Spectrum Professional Grade Wired Wireless Gaming Mouse support page under Downloads / G HUB. Here is the link.

3. If your gaming mouse is connected then G HUB should recognize your device once G HUB is installed.
Here is the G HUB User Manual PDF.
This is a quick fix if you encounter a problem with G HUB suddenly not finding your device (after it was previously working) and you don’t have time to uninstall/reinstall G HUB software.
