Serial Port Driver X64 Top — Mtk Usb

Download the SP Flash Tool v5.2308 package or Maui META v10.0. The Driver folder inside these tools contains the most up-to-date x64 binaries.

Unlike Qualcomm devices that use bulk Ethernet or QDLoader ports, MediaTek devices enter a special Preloader or Download (DA) mode when powered off and connected via USB. This mode presents itself as a serial COM port to your PC.

Without the correct x64 serial driver, Windows cannot communicate with the chipset, causing: mtk usb serial port driver x64 top

A proper x64 driver solves these problems by enabling low-level serial communication between your PC and the MTK boot ROM.

Follow these steps to install the driver without breaking your Windows boot configuration. Download the SP Flash Tool v5

  • Run Install.bat (if using Auto Installer) as Administrator
  • If manual: Update driver via Device Manager → Let me pick → Have disk → Select .inf for usb2ser_4in1.inf or mtk_usb_port.inf

    • | Problem | Likely Cause | Top Fix | |---------|--------------|---------| | Driver installs but device disappears after 3 seconds | Missing preloader handshake | Use the Preloader VCOM driver (Method B) | | Error 10 (Device cannot start) on COM port | IRQ conflict or incorrect baud rate | Force COM port to COM1–COM4 in advanced settings | | “Driver is not intended for this platform” | Trying to install 32-bit .inf on x64 | Use x64-specific .inf (look for “amd64” inside the file) | | Windows blocks install with “Hash mismatch” | Driver signature expired | Disable driver signature enforcement (temporary) |
