To get a Solid State System (3S) SSS6697 B7 USB mass storage device working again, you typically need to address either a driver conflict or corrupted firmware. The SSS6697 B7 is a common controller chip found in older flash drives like the Kingston DataTraveler G3 . 1. Fix via Device Manager (No Data Loss) If the drive is physically fine but not appearing in "This PC," try refreshing the driver and power settings: Update/Refresh Driver : Right-click Start and select Device Manager . Expand Universal Serial Bus controllers . Right-click USB Mass Storage Device and select Update driver . Choose Browse my computer for drivers , then Let me pick from a list... and select the standard driver. Power Management Fix : In Device Manager, double-click the USB Mass Storage Device . Go to the Power Management tab. Uncheck Allow the computer to turn off this device to save power and click OK . 2. Assign a Drive Letter If the drive is detected but hidden, it may just need a letter: Right-click Start and open Disk Management . Find your USB (listed as a Removable Disk ). Right-click the partition and select Change Drive Letter and Paths . Click Add and assign a letter like "E:" or "G:". 3. Firmware Repair (Data Will Be Erased) If the drive is "write-protected" or shows "No Media," the controller's firmware might be corrupted. You will need a Mass Production (MP) Tool specifically for the SSS6697 B7: Find the Tool : Look for the 3S USB Mass Production Utility or MPTool compatible with SSS6697 B7. How to Use : Run the tool as an Administrator. Insert the USB drive. The tool should display the chip ID (SSS6697 B7) and Flash ID. Click Start to re-flash the controller and format the drive. Warning : This process completely wipes the drive and can "brick" it if the wrong firmware version is used.

How To Fix A USB Mass Storage Device Problem - Full Guide
The SSS6697-B7 is a USB 2.0 mass storage controller manufactured by Solid State System (3S) . It is commonly found in budget-friendly flash drives from brands like Kingston (notably the DataTraveler series) and Toshiba. If you are encountering errors such as "Disk is write-protected," "Please insert a disk," or if the drive is not recognized at all, your controller firmware may be corrupted. Getting an SSS6697-B7 device to work again typically involves either software-level driver fixes or deep-level firmware restoration using Mass Production Tools (MPTools). Common Issues with SSS6697-B7 Controllers Write Protection: The drive refuses to format or delete files, claiming it is write-protected. No Media Error: Windows recognizes the "USB Mass Storage Device" but shows "No Media" in Disk Management . Device Not Recognized: The drive does not appear in File Explorer, often due to a Device Manager error (Code 10 or 43).

Here’s a concise technical review of the SSS6697-B7 USB mass storage controller based on common findings from data recovery forums, low-level formatting tools, and USB flash drive teardowns.
Overview The SSS6697-B7 is a USB 2.0 mass storage controller chip from Solid State Storage (SSS) , often found in budget USB flash drives (e.g., some Kingston DataTraveler, PNY, and generic drives). It’s a single-chip solution for TLC/MLC NAND flash. sss6697 b7 usb mass storage work
Performance & Reliability
Speed : Typically reads at ~15–25 MB/s, writes at ~5–10 MB/s (USB 2.0 max). Poor for large files; okay for small document transfers. Reliability : Mixed. Drives with this controller often fail sooner than those using Phison, SMI, or Alcor controllers. Known for sudden “0 MB” capacity or “USB device not recognized” issues after power loss or unsafe ejection. Power draw : Slightly higher than average for USB 2.0, leading to occasional enumeration problems on low-power ports or USB hubs.
Compatibility & Driver Support
OS support : Works with Windows (XP to 11), macOS, Linux out-of-the-box as a standard USB mass storage device. No special drivers needed. Chipset quirks : Some USB 3.0 hosts (especially older ASMedia or VIA chips) have trouble negotiating USB 2.0 mode with this controller, resulting in no device detected.
Low-Level Tools & Firmware
MPTool (Mass Production Tool) : SSS 6697 series tools exist (e.g., MP_Ver2162_6697 ), but are hard to find and often require specific firmware versions matching the NAND flash ID. Wrong settings can brick the drive. Recovery difficulty : If the controller enters “panic mode” (e.g., corrupted firmware), standard Windows format tools fail. You’ll need to short specific test points (TP) on the PCB to force factory mode, then use MPTool – not beginner-friendly. No official firmware updates : Manufacturers rarely provide end-user firmware upgrades for this controller. To get a Solid State System (3S) SSS6697
Common Failure Symptoms
Drive shows “0 bytes” in Disk Management. Windows asks to format, but format fails. Device disappears after writing large files. Read-only mode without physical switch.
