# xgecu-t48-reverse: reconstructing the T48 eMMC USB protocol

> xgecu-t48-reverse reconstructs the XGecu T48 programmer's eMMC USB exchange from Xgpro.exe analysis and captured device traffic. Its notes describe command opcodes, endpoint roles, bulk transfers and ISP settings; Python examples read and write eMMC through the T48 adapter.

## Requirements & limits

- **Prerequisites:** Python 3 and pyusb; a T48 and eMMC-ISP adapter are needed for hardware operations.
- **Testing evidence:** The author reports 1-bit, 3.3 V ISP reads and writes on real hardware; 1.8 V operation has not been checked on hardware.
- **License:** MIT license.
