Here’s a helpful feature-style breakdown of the – a term that often appears in device manager or driver contexts, especially with Samsung phones/tablets using Exynos chips.

If the USB controller is also active, this bug multiplies the problem. The phone may not be able to properly adjust its power consumption when the USB data lines are hot, and the thermal driver can get stuck in an incomplete cooling state. The Linux kernel developer Lukasz Luba, who worked on fixing this issue, observed that the temperature can “reach hot/critical trip point and shut down the device” if the governor fails to intervene correctly. If the error occurs at the same point every time (e

If your device is stuck in this state and overheating, follow this sequential debugging process to prevent permanent hardware destruction. Step 1: Immediate Thermal Mitigation

In this state, the phone exposes itself to a PC as SEC, SYSTEM LSI Exynos USB Device 4.0.0.0 . Because this low-level mode lacks sophisticated thermal management software, the Exynos SoC (System on Chip) or its integrated modem can pull unrestricted current via the USB cable. This results in a localized thermal runaway event at the USB port or the motherboard itself, often throwing "USB device overcurrent status detected" errors on the host PC.

If the device briefly cuts power, watch the Windows Device Manager to see if the listing disappears.

When Jax plugged the device into his console, his "Lifestyle & Entertainment" suite didn’t just load; it integrated .
