The truth is that the is neither a malfunction nor malware. It is a direct gateway into the low-level engineering and recovery modes of Samsung’s Exynos-based devices. This article will explore everything you need to know about this driver: what it is, why it appears, how to fix it, and how advanced users can leverage it for unbricking, data recovery, and custom development.
If your computer detects an "Exynos Usb Device" with a yellow exclamation mark in the Device Manager, you may need to install this specific driver manually. SEC, SYSTEM LSI Exynos USB Device 4.0.0.0 - DriverMax
Samsung continues to update this driver. As of 2025, newer Exynos chips (e.g., Exynos 2200, 2400) and Windows 11’s improved USB4 support have led to driver versions like 4.1.2.0 or 5.0.0.0 . The 4.0.0.0 tag is now considered legacy but remains widely deployed due to long-term support for older devices (Galaxy S8/S9/Note9/A50, etc.). Exynos Usb Device-4.0.0.0-
On modern Windows systems (Windows 10/11), drivers must be digitally signed. Older versions of Exynos drivers or custom modified drivers may trigger a CODE 52 error. The 4.0.0.0 build is generally a signed release, ensuring stability.
The string refers to a specific USB driver or device identifier associated with Samsung’s Exynos line of system-on-chips (SoCs). Exynos processors power many Samsung Galaxy smartphones, tablets, and wearables (e.g., Galaxy S series for non-US markets, A series, and older Note devices). The truth is that the is neither a malfunction nor malware
This driver is also part of the Linux kernel. Developers have worked on several patches to improve its functionality, such as a workaround for device tree binding conflicts on Exynos-based boards. Additionally, kernel patches have been made to support newer Exynos SoCs like the Exynos7885 and Exynos 2200 (found in the Galaxy S22+), showing Samsung's ongoing commitment to Linux support for its hardware.
When a Samsung Galaxy or Exynos-powered device experiences a catastrophic software failure (e.g., an interrupted OS update or corrupted partition table), it fails to boot into standard Android or the traditional Odin "Download Mode". In these emergency scenarios, the processor defaults to its core boot-recovery state. Connecting the device to a PC in this state triggers the system to look for the Exynos USB Device 4.0.0.0 driver to establish a recovery channel. 2.
