Method B: The Dedicated Tool – "MPtool" (Mass Production Tool)

This is the specific solution for SSS6697-B7. You cannot use a generic USB formatter. You need the 3S USB Mass Production Tool.

What you need:

• A Windows 7 or Windows 10 (with testsigning mode enabled) PC.
• Version specific: Look for SSS_MP_Utility_v2.173 or SSS 6697 Tool v2.162. Do not use v2.150 or lower; they do not support the B7 revision.
• The .INI file: You need a configuration file set to SSS6697-B7.

Step-by-Step:

1. Disable Driver Signature Enforcement (Windows 10/11):

   • Restart your PC.
   • Press Shift + Restart → Troubleshoot → Advanced Options → Startup Settings → Restart.
   • Press F7 (Disable driver signature enforcement).
   • Note: You must do this every time you run the tool.

2. Download the Correct MPtool.

   • Search for SSS6697-B7 MPtool v2.173.rar.
   • Extract the folder to C:\MPTool (Avoid Desktop; long file paths cause errors).

3. Configure the Tool:

   • Run MPTool.exe as Administrator.
   • Click "Setting" (Password is usually 123456 or 320).
   • Go to "Scan Setting" → Set to "Normal Mode."
   • Go to "Partition Setting" → Ensure "Format" is checked.
   • Go to "LED Setting" (Optional but useful for debugging).
   • Most Important: Under "Controller," manually select SSS6697-B7. If it is not listed, you have the wrong version.

4. Run the Process:

   • Click "Start" or "Space Start."
   • The bar should turn Yellow (Downloading firmware), then Green (Success).

5. Post-Success:

   • Unplug the USB drive.
   • Wait 10 seconds.
   • Plug it back in. Windows should detect a fresh USB mass storage device.

For developers: implementing or debugging a USB-MSC bridge (practical notes)

• USB descriptors:
  • Ensure device class code = 0x08 (Mass Storage); subclass 0x06 (SCSI), protocol 0x50 (Bulk-Only) for BOT.
  • Provide correct configuration and endpoint descriptors (one bulk IN, one bulk OUT).
• Implement SCSI command processor:
  • Support INQUIRY, TEST UNIT READY, READ CAPACITY(10/16), READ(10), WRITE(10), REQUEST SENSE, MODE SENSE as minimum.
• Handle BOT protocol:
  • Implement Command Block Wrapper (CBW) and Command Status Wrapper (CSW) correctly with proper signatures and tags.
• UAS support:
  • For UAS, implement USB 3.0 endpoints, adhere to UAS command set, and provide proper UAS descriptors if targeting high throughput.
• Concurrency and buffering:
  • Implement proper scatter/gather and multiple outstanding commands for UAS.
• Power management:
  • Correctly respond to USB suspend/resume and implement safe flush of volatile caches on power loss.
• Testing:
  • Use Wireshark with USB capture, usbmon (Linux), or bus-powered analyzers to trace USB traffic.
  • Validate with host tools: sg3_utils (sg_inq, sg_turs), Linux usbtest, and mass-storage compliance suites.

Summary

“sss6697 b7” likely denotes a USB mass-storage bridge/chip identifier. Problems typically stem from firmware, power, cable, driver (UAS vs BOT), or failing media. Follow a methodical diagnostic path (logs → cable/port → host OS → driver/firmware → hardware inspection), image critical data first, and apply fixes such as switching drivers, updating firmware, or replacing hardware when appropriate.

2. "Mass Storage" Mode

When you plug a drive with this controller into a PC, it identifies itself as a USB Mass Storage Device.

• Standard Protocol: It uses the standard USB Mass Storage Class (MSC) protocol.
• Driver Requirement: Because it follows the standard class specification, it typically does not require proprietary drivers. It uses the generic usbstor.sys driver built into Windows, macOS, and Linux.
• Identification: You can see the controller ID in tools like ChipGenius or USBDeview. The ID usually appears as VID = 0951 (often Kingston, though clones vary) and PID = 1666 or similar, but the specific hardware ID for the controller internals is what mass production tools look for.
