What is the HS-USB Diagnostics 9002 Windows Driver?
The HS-USB Diagnostics 9002 driver is typically associated with devices using the Qualcomm chipset, especially in relation to USB diagnostic ports used for communication with mobile phones, modems, or other devices that require diagnostic functions. The HS-USB (High-Speed USB) part of the name indicates that it's a USB-based driver, and the 9002 refers to a specific Qualcomm device identification number or chipset used for USB diagnostics.
This driver is often seen when you are connecting a Qualcomm-based Android phone or other mobile device to your computer, either for tasks like debugging, flashing firmware, or using ADB (Android Debug Bridge) over USB. When your phone is connected in "diagnostic mode," the HS-USB Diagnostics 9002 driver allows Windows to properly interface with it.
