Electrical Interrupt\n   └─ The USB host controller hardware registers the incoming bytes and flashes a physical voltage line (IRQ).\n4. Interrupt Controller Handling\n   └─ The APIC captures this interrupt signal and sends a priority alert line to the active CPU Core.\n5. CPU Context Jump\n   └─ The CPU core halts its active program loop, looks up the target vector in the IDT, and drops into Ring 0.\n6. Interrupt Service Routine Run\n   └─ The Kernel's dedicated keyboard driver ISR reads the raw scan code directly from the controller's MMIO register.\n7.

Thread Scheduling Forwarding\n   └─ The kernel wakes up your operating system's window manager application and places character packets into its message queue.\n9.
