Exynos Usb Device-4.0.0.0- Jun 2026
The is a specific Windows virtual COM port driver used primarily for low-level communication with devices running Samsung Exynos system-on-chip (SoC) architectures. Developed by SEC, SYSTEM LSI (Samsung Electronics Corporation's System Large Scale Integration division), this system component establishes a data link when a smartphone, tablet, or specialized development board is booted into a low-level hardware interface mode, such as USB Download Mode (USB-DL) or Exynos Emergency Boot (EUB) .

With Samsung increasingly moving to Snapdragon chips in global markets (Galaxy S23, S24 series), and the new Exynos 2400 featuring a more locked-down USB stack, the classic interface is disappearing. Modern Exynos devices now use a more secured USB mode that enumerates as Exynos USB Device (Runtime) or integrates with Google’s fastbootd. However, legacy devices (Galaxy S7 through S21 FE) will continue to rely on this interface for years. Exynos Usb Device-4.0.0.0-
Press and hold the buttons simultaneously for at least 15 seconds.
Samsung Exynos processors power a wide range of mobile devices, from flagship smartphones to embedded development boards. A fundamental requirement for these systems is robust Universal Serial Bus (USB) connectivity. The identifier Exynos USB Device-4.0.0.0- typically appears within operating system logs, hardware abstraction layers (HAL), or Windows Device Manager properties.
Tools like can automate the process. They scan your PC for missing drivers and automatically download and install the correct Exynos USB Device drivers. While convenient, caution is advised when using third-party applications. The is a specific Windows virtual COM port
Occasionally, an error occurs where standard USB flash drives or storage devices connected to specific laptops (such as certain MSI or Intel-based motherboards) are improperly assigned this driver profile. When Windows mistakenly matches a flash drive to the VID_090C&PID_1000 identifier, the drive becomes unresponsive and gets locked out of standard file systems. How to Install the Driver Correctly
The driver is a vital low-level software component developed by Samsung Electronics' System LSI division . It manages communication between a Windows PC and hardware running on Samsung Exynos mobile chipsets.
You will typically encounter this connection state when using Samsung Odin, flashing custom ROMs, utilizing specialized service boxes (like Z3X or Chimera), or when a device suffers from a hard brick (broken bootloader).
