| Attribute | Value | |-------------------|-------------------------------------| | Vendor Name (claimed) | “Unknown” or “Generic” | | Common Device Type | USB-to-Serial (UART), USB-JTAG, or ISP programmer | | Typical Chip | Unknown Chinese clone of FTDI, CP210x, or CH340 | | Linux Kernel Module| ch341 , usbserial , ftdi_sio (fallback) | | Windows Driver | Often uses usbser.sys or requires a specific .inf file from manufacturer |
The appearance of this identifier is almost always the result of a . Several specific scenarios can trigger it: usb device id vid ffff pid 1201
Right-click the extracted executable (usually FirstChip_MpTools.exe ) and select . However, is technically a fallback code or placeholder
Under standard manufacturing processes, the values are distinct. However, is technically a fallback code or placeholder value often registered to unbranded "Taiwan OEM" batches or generic chips. When paired with PID_1201 , it almost universally indicates a flash memory controller manufactured by FirstChip (specifically models like the FC1178 , FC1178BC , or FC1179 ) running under a default, unconfigured, or generic firmware layer. Why Is Your USB Drive Showing This ID? Seeing this specific Vendor ID (VID) and Product
Seeing this specific Vendor ID (VID) and Product ID (PID) combination is a clear indicator that something is amiss. This hardware footprint points directly to unbranded, generic, or corrupted flash memory storage drives—frequently built using budget controllers.
