@wlinn751 I'm experiencing the exact same issue using an LG B7 65"

In its current state ACV XBox series X port cannot be played with a keyboard and mouse, but with only a keyboard OR a mouse.

Troubleshooting:

1. I plugged the mouse into the top USB port and the keyboard into the bottom. ACV only recognizes the mouse. I verified that keyboard is recognized and works fine in other applications.
2. I tried toggling between hybrid and mouse + keyboard input modes in the menu. The issue remains.
3. I swapped device order in the XBox (by plugging the keyboard now into the top USB port and the mouse into the bottom) and ACV then recognized my keyboard but the mouse input stopped working. Again, both devices still work simultaneously in other applications.
4. I further tested by plugging a USB hub into the top port with both devices plugged into that hub and again only the first device plugged into the hub is recognized. It appears that the XBox Series X port of ACV only recognizes one USB device at a time, and specifically only the lowest device ID.

@magaara Unfortunately no. I'm assuming it's pretty rare that XBox players are trying to play using keyboard + mouse, otherwise we'd probably be seeing more reports.

Update: Narrowing down the issue,

1. I swapped device order in the XBox (by plugging the keyboard now into the top USB port and the mouse into the bottom) and ACV then recognized my keyboard but the mouse input stopped working. Again, both devices still work simultaneously in other applications,
2. I further tested by plugging a USB hub into the top port with both devices plugged into that hub and again only the first device plugged into the hub is recognized. It appears that the XBox Series X port of ACV only recognizes one USB device at a time, and specifically only the lowest device ID.

Thus in its current state ACV XBox port cannot be played with a keyboard and mouse, but with only a keyboard OR a mouse.

I just wanted to add that I tried toggling mouse+keyboard and hybrid modes for input devices to no avail

Mouse input is working just fine but keyboard input is not being recognized. The game is detecting a keyboard is plugged in and changing menu items accordingly (e.g., press space to continue) but the key presses are not registering. I can confirm that the keyboard is working in other games and applications.
