• Modern operating systems already contain the USB Mass-Storage Class (MSC) driver; no additional “driver” exists for a pendrive labelled “USBDISK modelo: NAND”.
• If the stick is detected with VID = FFFF, PID = 1201, capacity = 0 GB or a generic name such as “NAND USB2DISK”, the problem is an internal firmware failure of the controller (most often a ChipsBank CBM20 9x/21 9x family).
• The only realistic solution is to re-flash the controller with its factory Mass-Production Tool (MPTool/UMPTool/APTool). Ordinary Windows drivers, generic format utilities or Device-Manager re-installs will not repair the fault.
USB architecture
• A USB flash drive contains
– A micro-controller (e.g. ChipsBank CBM2099, CBM2199…)
– One or more raw NAND flash dies
– Controller firmware stored in hidden area of the NAND
• During normal enumeration the controller presents its programmed VID/PID and Logical Block Address table to the host, which then loads the standard MSC driver (usbstor.sys, usbstor.inf, usbhid.sys in Windows).
• If the controller fails to read its own firmware, it switches to “bootloader / recovery” mode and reports the default VID = FFFF, PID = 1201 and 0 bytes capacity. At this point the OS driver is functioning correctly; the flash-drive itself is not.
Why a downloadable “driver” will not help
• The VID/PID table that Windows uses to match an INF file is missing, so no third-party INF can bind.
• Even if you forced a different driver (libusb-win32, WinUSB), the controller cannot translate logical reads/writes to NAND page operations because its firmware mapping tables are gone.
• Therefore the cure is to re-initialise the controller with factory software that:
– Downloads a temporary loader over USB,
– Detects the NAND type/geometry,
– Scans for bad blocks,
– Writes a fresh firmware image and rebuilds the LBA map.
Controller identification (essential)
• Plug the device and run one of:
– ChipGenius (preferred)
– ChipEasy
– Flash Drive Information Extractor (FDIE)
• Even in bootloader mode these tools usually disclose the controller string, e.g. “ChipsBank CBM2199A”. Note it exactly; MPTools are controller- and sometimes NAND-specific.
Obtaining the correct Mass-Production Tool
• Community repository: https://www.usbdev.ru/files/chipsbank/
• Select the tool matching your controller:
– CBM209x_UMPTool
– CBM2199_UMPTool / APTool
– CBM23xx_APTool, etc.
• Download several versions if unsure; later revisions may drop support for older silicon, so trial-and-error is common.
Flashing procedure (generic outline)
Failure modes
• “Detect Flash ID Error” → tool incompatible; try another version.
• “Bad Block > limit” → worn-out NAND; drive is beyond economic repair.
• No detection at all → controller dead or PCB damaged; software cannot help.
Data recovery considerations
• MPTool rewrites the entire NAND → irreversible data loss.
• If data is valuable, stop and consult a professional chip-off recovery lab before any MPTool attempt.
• Latest publicly leaked ChipsBank tools (as of 2024-05) are UMPTool V7200 and APTool V7300, both available at usbdev.ru.
• Newer controllers (CBM2460, CBM2380) support USB 3.2 Gen1 and require corresponding APTool, not legacy UMPTool.
• Growing trend: vendors add secure-firmware signatures; future consumer drives may refuse unsigned MPTools, limiting DIY repair.
• Think of the controller firmware as the “BIOS” of the flash drive. Without it, the host still provides power and generic USB support, but the storage subsystem inside the stick is brain-dead.
• VID FFFF is a reserved test value much like MAC 00-00-00-00-00-00 in networking—it signals “identity unknown”.
• Distributing proprietary MPTools may violate vendor NDAs; most community sites operate in a grey area. Download and use at your own risk and comply with local copyright law.
• Flashing tools run in elevated mode and have direct hardware access—obtain them only from reputable sites to avoid malware-laced archives.
• Always inform end-users that the process erases data; obtain consent if working on third-party devices.
Best practices
• Use an isolated PC or VM when running MPTools.
• Connect the pendrive directly to a rear-panel USB port—not through a hub—to avoid enumeration glitches.
• Disable real-time antivirus temporarily; some MPTools load unsigned drivers that AV will quarantine.
• Document every parameter before you click “Start” so you can replicate success or diagnose failure.
Potential challenges & mitigation
• Wrong tool version → prepare multiple releases beforehand.
• Password-protected settings → search in the tool’s .ini or readme.
• Power instability during flash → use a powered USB port; avoid laptops on battery.
• If after several tool variants the device still reports 0 GB, the NAND is likely physically damaged—replacement is cheaper than further labour.
• Some fake-capacity drives masquerade as larger sizes; after firmware rewrite they reveal the real (much smaller) capacity. This is not a bug but exposure of prior fraud.
• Monitor usbdev.ru and flashboot.ru for newer MPTool releases.
• Explore open-source controller reverse-engineering projects (e.g., pyusb-based flasher prototypes) which aim to provide safer, audited alternatives to closed MPTools.
• Study JEDEC UFS trends; USB thumb-drives may migrate to UFS-based controllers in coming years, changing repair methodology.
Your “USBDISK modelo: NAND” pendrive does not need an operating-system driver; it needs its own internal firmware restored. Identify the exact controller (usually ChipsBank), download the corresponding Mass-Production Tool, and re-flash the device. This process fixes many 0 GB / VID FFFF failures but destroys any existing data and cannot help if the NAND or controller is physically dead.
