IR receiver eHome missing

Hi,

I've been running my HTPC on windows 10 (current version 2004) for a number of years and it has worked fine. However, yesterday my Logitech remote ceased working. I did the usual things , switch off switch on etc.

When I opened my Device Manager i noticed that the eHome device is missing.
The usbcir.sys file exists under %WinDir%\System32\drivers\usbcir.sys.
A check of the event logs show NO errors.

This link http://batcmd.com/windows/10/services/usbcir/

States that if usbcir fails to start it should throw an error.
I have no errors.
i ran the batch file RestoreEHomeInfraredReceiverUSBCIRWindows10.bat from this site but no luck even after a reboot.

Not sure if this is a service or not. I couldn't find a eHome service running on my machine.

Does anyone know why this device is no longer available or showing up under the device manager ?
How can i re-install it ?

I can't suggest a fix, but I wonder if you found a solution.

it was two years ago and i don't know how i fixed it but fix it i did. If you have a solution post it here in case i need it again in the future.

I have two identical mini-pcs that depend on the eHome driver being properly installed. On the first one, like you, I struggled to get Windows to identify the transceiver properly, then one day it started working, and I had tried so much that I didn't really know what the cause was. However, on the second installation, I FINALLY found the Microsoft eHome transceiver driver.

If you only have the transceiver plugged in, Windows lists it as a USB Input Device, and you go through Device Manager's update driver routine, look for a driver manually, then uncheck the box for "Show Compatible Hardware". The eHome driver is in the list, and you can install it, although with dire warnings. In my case the warnings were warranted, because as soon as the driver was loaded the mouse and keyboard stopped working. I've tried a zillion different combination of setups, but as soon as the transceiver is plugged in, the other inputs stopped responding. Unplug the transceiver, and everything worked.

I had set a restore point before installing the driver, so I backed off to the previous setup, but it was a step in the right direction. The problem is... how do you proceed with testing if you have no input device? It even disables input from remote control software.

I'm using Windows 11 so the drivers should be up-to-date. If it's using the USBCIR.SYS driver, then the version is dated 2022. But...I can't tell what the driver is because I can't use an input device to check!

I'll let you know what I find.
