Establishing a connection with Huawei smartphones in their lowest-level hardware mode is a common task for mobile engineers. This is where the Huawei USB 1.0 Driver comes into play. Unlike standard MTP or ADB drivers, this serial port driver is designed to work when the phone is forced into “COM 1.0” mode, typically through a physical test point or a specialized Harmony/EDL boot cable.
This driver is essential for older and mid-range Huawei and Honor devices where the Kirin processor needs to be accessed directly for critical operations like factory reset, bootloader repair, or recovering from a “System has been destroyed” state. Having the correct version installed prevents the dreaded “USB Device Not Recognized” popup in Windows during these high-stakes repairs.
Essential Use Cases for Mobile Technicians
The USB 1.0 port is the ultimate failsafe for Kirin-based devices. You will need this driver in the following professional scenarios:
- Full System Recovery: Flashing a device that no longer boots into Fastboot or Recovery mode and appears as a “HUAWEI USB COM 1.0” port.
- FRP Lock Bypass: Connecting to service tools like UMT, Chimera, SigmaKey, or EFT Pro to remove Google account locks.
- Hardware Test Point: When you physically short the board pins to trigger the emergency serial port for deep repair.
- Writing Board Software: Installing factory-level board firmware to fix corrupted partition tables or “Software Install Failed” errors.

How to Manually Install the Huawei USB 1.0 Port
Sometimes the auto-installer might miss the specific COM port assignment depending on your Windows update status. Follow these manual steps for a 100% success rate in your workshop:
- Fetch the Setup: Access the driver ZIP archive from the link provided in the next section.
- Extract: Unpack the contents to your desktop or a dedicated “Drivers” folder for easy access.
- Connect Device: Short the test point pins on the motherboard and plug in the USB cable. In Device Manager, look for “USB SER” or “Unknown Device.”
- Update Driver: Right-click the unknown item, choose “Browse my computer for drivers,” and manually select the extracted folder.
- Confirm: Windows will list it as “Huawei USB COM 1.0.” Ensure there is no yellow exclamation mark next to the entry.

Common Error Fixes & Advice
Code 10 or Code 43 Error: If you see these errors in Device Manager, it is usually a hardware issue or a poor cable connection. Try a different USB port on the motherboard (always use the rear ports on a desktop PC) rather than the front panel. Also, ensure your tweezers are actually touching the ground shield when attempting a test point short. If the device reboots instantly, the shorting was not held long enough during the cable insertion phase.
Frequently Asked Questions (FAQs)
Q: Will this driver work for Kirin 980 or 990?
A: While this is the standard 1.0 driver, newer Kirin chips (980/990/9000) often require the “Huawei Harmony” driver pack or a specialized Harmony cable to be detected correctly in service mode.
Q: Does this driver require a reboot?
A: Yes, we strongly recommend a reboot to allow Windows to properly initialize the new serial communication port.
