These devices often identify themselves as "NAND USB2DISK" with a capacity that might show as 0GB when failing. Why You Are Seeing This
Tools like the , USB Ninja , or Arduino-based HID emulators often allow custom VID/PID. Attackers sometimes set VID=FFFF to avoid leaving a traceable vendor name or to evade basic security scans. A PID=1201 could be a specific firmware payload for keyboard emulation or storage.
or "Disk Not Found" despite the computer playing the USB connection sound.
Plug in your drive, launch either utility, and look for these critical fields: usb device id vid ffff pid 1201
A drive purchased as "2TB" or "64GB" suddenly reveals its true capacity of 128MB to 32GB after a firmware crash or a flash reset.
Do not be alarmed if your "128GB" drive suddenly completes formatting as a . This means the tool successfully saved the usable section of the drive while discarding the fake capacity sectors.
Try a different USB port or a different computer to rule out power-supply issues. These devices often identify themselves as "NAND USB2DISK"
It is a reserved, invalid, or "null" VID in official specifications. This immediately raises red flags.
Before attempting any firmware fixes, you must assess data priority.
: A multi-byte hex string (e.g., 98 00 A0 82... ) that reveals the actual manufacturer of the physical memory storage. Step 2: Download the Correct Mass Production Tool A PID=1201 could be a specific firmware payload
While these IDs are not assigned to a legitimate manufacturer in official databases like Linux usb.ids , they are frequently seen in the following scenarios: Firmware Failure:
Often appears in Device Manager or system logs as USB\VID_FFFF&PID_1201 . Common Use Cases and Reliability
