If driver installation works and the device shows as Qualcomm HS-USB QDLoader 9008 , you can attempt a flash using QFIL.
I know how difficult it can be to source bulk QUSB units that actually match their reported CID (Card Identification) registers. A mismatched CID can brick a project or cause massive headaches with OEM software locks.

Conclusion “qusb bulk cid verified” is a concise status marker from Qualcomm-related USB stacks signaling that a bulk transfer channel identified by a CID has passed verification and is ready for use. It’s primarily useful for debugging and development around data channels, flashing, or diagnostic interfaces on Qualcomm devices: its presence usually means the handshake succeeded, while related negative messages help narrow down connectivity, configuration, or authentication issues.

If your hardware locks to the CID (common in navigation systems, embedded Linux boards, or proprietary industrial controllers), these units are ready to go. No fake CIDs, no generic relabels.
The major obstacle for DIY recovery is the (also known as prog_emmc_firehose.mbn ). This is a proprietary, device-specific file that acts as the bridge between the flashing tool (QFIL) and your phone's storage chip.
The status is a vital diagnostic milestone in deep-level Android repair. It serves as a green light, indicating that the device’s brain (the Qualcomm SoC) and its memory vault (the flash storage) are still structurally sound and communicating. By installing the correct Qualcomm drivers and matching the device with its appropriate factory firehose firmware, you can reliably revive a device from this state.
When an Android smartphone, tablet, or embedded system powered by a Qualcomm Snapdragon processor fails to initialize its primary operating system or secondary bootloader (SBL), it falls back to a primary bootloader (PBL) routine executed directly from the silicon's Read-Only Memory (ROM).
