The presence of this driver has security relevance: qusb bulk cid driver
A QUSB bulk CID driver is software that enables communication between a host (typically a computer or embedded system) and Qualcomm USB (QUSB) devices using bulk transfer endpoints to exchange Card Identification (CID) or similar proprietary control/data frames. This driver bridges the USB stack and a device-specific protocol carried over USB bulk pipes when the device does not use standard USB classes (e.g., CDC, HID, MSC). These drivers are common in modems, fast-charge controllers, and diagnostic interfaces where Qualcomm-based devices expose a custom command channel. : If successful, the entry will move to
: Use Qualcomm HS-USB QDLoader 9008 driver (version 2.1.2.0 or similar). These drivers are common in modems, fast-charge controllers,
: Recognize hardware IDs such as USB\VID_05C6&PID_9008 , which typically appear as "QHSUSB_BULK" or "QUSB_BULK_CID" in the Device Manager.
The (Chip Identification) driver is a specialized interface used primarily when a device is in a low-level state. This is most common when:
