If you have found the correct software version (compatible with the B7 firmware), follow these steps to restore the drive:
It handles the movement of data using the High-Speed USB 2.0 protocol (up to 480 Mbps).
Technically, the chip is identifiable through its unique . Typically, devices using this controller report a VID of 0C76 and a PID of 0005 (or similar variants). This identification is critical because it directly informs the user’s software environment—especially low-level formatting and repair tools—about the controller’s command set. Without correct identification, a host computer cannot issue the proprietary "vendor commands" required to manipulate low-level flash parameters. sss6697 b7 usb mass storage work
The working principle of the SSS6697-B7 revolves around three core processes: enumeration, translation, and error handling.
is widely reported to be unstable and prone to failure. Common issues include: If you have found the correct software version
Once you have located the correct MPTool, follow these general steps (note that exact UIs vary by software version):
: If the drive is completely unrecognized by your PC, you can manually force the controller into a safe engineering mode. Open the plastic casing of the USB drive, find the SSS6697 B7 chip, and use a precision needle to carefully short-circuit pins 29 and 30 (the data lines) while plugging it into the computer port. Release the short circuit immediately once the PC makes a connection sound. This bypasses the corrupted firmware loop and forces the controller to accept a fresh binary file. This identification is critical because it directly informs
If your computer fails to even recognize the drive so you can use the MPTool, the issue might be related to your operating system or physical connection rather than the firmware. 1. Check Device Manager
The solder balls anchoring the compact single-channel chip package to the PCB can break down over years of thermal cycling. This severs communications lines to the flash memory array, meaning the system can see the controller but fails to identify any available memory storage medium. 3. Initial Software and OS-Level Diagnostics
