kernel: USBMSC Identifier (non-unique): 0xffff 0x1201 0x0
If you find ffff:1201 on a physical computer:
When your operating system reads VID: FFFF PID: 1201 , it points to two primary scenarios:
This happens because fraudulent manufacturers alter the internal controller settings to report a false size to your operating system. Once the real FirstChip factory utility cleans the drive, it locks down the unstable, non-existent storage sectors, leaving you with only the true, physical storage capacity of the flash chip. If you need help finding the exact tool or step, usb device id vid ffff pid 1201
These generic descriptors, together with the FFFF:1201 identifier, are a strong indication that the drive’s controller chip has failed or that its firmware has been erased or corrupted.
Such output confirms that the underlying controller is known, even though the reported identifiers are meaningless.
When the tool finishes, it displays a green success state and restores a valid, real vendor identification string. Safely unplug the drive, wait 5 seconds, and reconnect it to your computer. kernel: USBMSC Identifier (non-unique): 0xffff 0x1201 0x0 If
The OS treats VID_FFFF differently:
This fingerprint is almost exclusively associated with ultra-budget, unbranded promotional flash drives, fake-capacity drives bought on discount marketplaces, or generic storage sticks using low-cost controllers like the FirstChip FC1178, FC1179, or YC2019 architectures. Common Failure Symptoms

Once you know the controller model, search for the corresponding “MP tool” (mass production tool) from sources such as:
