Entering UEFN, the USB mouse starts disconnecting and reconnecting repeatedly, getting worse the longer you stay inside of the application until the mouse completely stops working. Switching to a new window fixes the issues but reappear once you get back into UEFN
Steps to Reproduce
Open an Island
Interact with the viewport for a bit
Expected Result
Mouse working correctly and doesn’t disconnect
Observed Result
The mouse starts disconnecting and reconnecting rapidly
Platform(s)
Windows 11
I have verified the files through the epic games launcher and restarted my computer three times, the problem persists
There were a lot of bugs that stacked up over the little time uefn has been around but this one has completely destroyed uefn for me and I can no longer work on my game. I have a deadline…
I’m sorry but this has nothing to do. Playing around with it more reveals that it is messing with most of my IO USB devices. Keyboard stops working, headphone’s microphone stops as well, along with the mouse like explained above.
wait…are you sure uefn is causing this? this has been happening to me and i was assuming my mouse was just going bad. my issue is a bit different though. I have a wireless mouse that disconnects and i cant use it unless i plug it in or restart my pc. if i unplug it (it is fully charged) it disconnects my mouse. i dont know when/why this happens. i can use my mouse wirelessly up until it disconnects, then im forced to have it wired. happens while working in uefn
Positiive, My input USB devices work perfectly fine and the second I enter UEFN the mouse starts to act up. I have video footage of the RGB light flickering the second I interact with the viewport.
