| Tool | Purpose |
|------|---------|
| lsusb (Linux) | Confirm VID=05C6 (Qualcomm), PID=9008 (EDL) |
| edl.py (Python) | Direct bulk read/write, no driver needed on Linux/macOS |
| QFIL | Needs QDLoader driver, works with QUSB_BULK_CID after proper driver binding |
| libusb bulk transfer | Custom scripts – send Sahara/firehose packets |
Use tool (e.g., QFIL, EDL.exe, or Python edl script): qusb bulk cid driver
# Using bkerler/edl (cross-platform)
edl --cid
Output example:
CID: 150100424A58345248015B83D3F15096
MID: 0x15 (Samsung)
PNM: "BJX4RH" (Product name)
PSN: 0x015B83D3
MDT: 09/2015
Host Device (EDL mode)

Qualcomm processors utilize a sophisticated USB gadget framework. Unlike standard PC drivers, Qualcomm drivers often manage the interaction between the high-level operating system (Android/Linux) and the low-level baseband processor (modem). "QUSB" acts as the umbrella term for these proprietary controller drivers. Use tool (e
