My CosmosOS doesn't detect keyboard input when running on a desktop PC (motherboard: ASUS P8B75-V)

I am a beginner in the OS development field (in my free time). After setting up some input features, everything worked fine on VMware. However, when I boot from a USB, it says:

Welcome to OS... Input: ==>but I cannot type anything with my keyboard.

According to ChatGPT, I already tried the following BIOS settings:

• Intel USB 2.0 Controller: Enabled
• Intel xHCI Mode: Disabled
• Legacy USB Support: Enabled
• EHCI Hand-off: Enabled

But it still does not work :(

Here is the code on GitHub:

Cosmos does not support USB, you must use PS/2, but it does look like "Legacy USB Support" should do USB to PS/2

Thank you!!!, I think it only supports PS/2 connections cus Legacy USB Support seem not working.
