Try a different USB cable—preferably the original Samsung cable that came with the phone. Also test the phone with a different charger. If the overheating disappears, the cable or charger is at fault. If the problem persists regardless of the cable, the issue is almost certainly inside the phone’s USB controller or battery.

To help diagnose the exact state of your hardware, could you share a bit more context? Please let me know:

This specific identifier typically surfaces when a device powered by an Exynos chipset experiences severe overheating localized around the USB controller or the physical USB-C port. The "Device 4000" nomenclature often correlates with internal hardware addresses or subsystem logs mapping the physical USB transceiver to the central processor. When this error manifests, users generally notice:

The isn’t about temperature – it’s likely a driver naming quirk or localization label (possibly from older Samsung USB drivers), meaning hot-pluggable or just a version tag. exynos usb device4000 hot

This article explores how Exynos-powered USB peripherals and devices (exemplified by high-end, 4000-series type interfaces) enhance lifestyle and entertainment through speed, connectivity, and superior multimedia processing. 1. Seamless Lifestyle Integration: The Power of Exynos USB

The most common culprit is a blown USB Hi-Speed IC or a damaged charging daughterboard. Fortunately, on most Exynos-powered devices, the USB port resides on a small, modular secondary board separate from the main motherboard. A technician can replace this daughterboard quickly and affordably, restoring your device to cool, efficient operation. Try a different USB cable—preferably the original Samsung

: Many high-speed USB flash drives or mobile chipsets (like the Samsung Exynos series) generate significant heat during sustained data transfers or high-intensity tasks. Physical Port Issues

Add usbcore.autosuspend=-1 to your kernel boot parameters in /etc/default/grub .

This issue is far from a simple software glitch. It represents a complex interaction between emergency hardware boot states, power management discrepancies, and physical thermal limitations. What is the Exynos USB Device 4.0.0.0 Connection State? If the problem persists regardless of the cable,

Carefully use a non-conductive plastic toothpick or a toothbrush to remove debris. 3. Replace Charger and Cable

If you do not want to modify your kernel, try the following software tweaks:
