Article: Phison PS2251-07 / PS2307 and MPTool — Overview, Usage, and Troubleshooting
Introduction
Phison’s PS2251-07 and PS2307 are USB flash drive controller families widely used in low- to mid-range removable storage devices. MPTool (Manufacturer/MP Tool) is the vendor-supplied utility used by manufacturers, repair technicians, and advanced users to program firmware, format, configure, and diagnose Phison-based USB drives.
The Controller That Launched a Thousand Fixes
Phison is a legitimate Taiwanese company that makes controllers (the "brains" of a USB stick). The PS2251-07 was a rock-solid, mass-produced controller found in drives from reputable brands like Kingston, Transcend, and SanDisk, as well as in thousands of generic "no-name" drives. phison ps2251-07-ps2307- mptool
2. Controller Identification
- Vendor: Phison Electronics Corp.
- Controller Model: PS2251-07 (Silicon revision: PS2307)
- Interface: USB 3.0 (backward compatible with USB 2.0)
- Common VID/PID: 0951:1666 (Kingston), 13FE:5500 (Generic), 0930:6544 (Toshiba)
- Common Issues: Drive showing 0 MB capacity, write-protected error, not detected, or extreme slowdowns.
The Good (What Works Well)
- Life Support for "Dead" Drives: The primary reason to use this tool is its ability to low-level format and reinitialize a drive that has become a brick. If your drive shows 0MB capacity, isn't detected, or has write-protection errors, this tool is often the only solution.
- Extensive Customization: The tool gives you raw access to controller parameters: you can change the USB device mode (removable vs. fixed disk), tweak LED behavior, adjust power consumption, and even create a CD-ROM partition for bootable tools.
- Vendor Support: Many common USB 3.0 drives (Corsair Survivor, certain Kingston DataTravelers) use this controller. The tool (versions like S11 or S16) reliably detects the flash chip and, with the correct firmware package, can rebuild the drive.
- Fast Low-Level Formatting: When it works, the "Erase Good Block" mode is significantly faster than standard Windows formatting for restoring full capacity.
Partitioning: Create hidden, read-only, or CD-ROM partitions. Article: Phison PS2251-07 / PS2307 and MPTool —
If you want, I can:
The Phison PS2251-07 (also known as PS2307) controller is a common component in high-speed USB 3.0 flash drives from brands like Kingston and Toshiba. When these drives become "read-only," unrecognized, or show "no media," they often require a Mass Production Tool (MPTool) to re-flash the firmware.
