I have a Logitech keyboard with trackpad that uses a Logitech unifying receiver. I am using an Android tablet as the host and a Windows 10 desktop as a client. I was able to use this keyboard with trackpad fine for years but it stopped working a couple weeks ago. It shows up in the VirtualHere Client and says it's in use, but the device does not respond to any input. I can then plug the receiver directly into the desktop and it works. A bluetooth receiver and Xbox One receiver continue to work fine through Virtualhere. Also, I tried a separate Logitech mouse that uses another unifying receiver and it also did not work. So it seems isolated to the Logitech devices.

I did, and saw several that referred to difficulties with Android and and mouse input. But those date back years and my issue only started a couple weeks ago. I also saw a reply you made to one of them stating to avoid plugging in a mouse directly and instead use something with a USB receiver, so I assumed the typical Android mouse issue applies to wired mice / keyboards.

I plugged my Logitech Unifying receiver into my pixel 4a(5G) and used it via virtualhere app and it works fine on my win11 client. Im wondering if perhaps the wrong speed is being detected on your android tablet. Plug the receiver into the tablet then open the virtualhere app. Click on the menu at the top right and select System Messages. Does it say "Found Full Speed Device [046d:c52b] Logitech, USB Receiver" ?
