Usb Device Id Vid Ffff Pid 1201 Guide

The Yellow Light

This device is used to provide absolute mouse positioning (rather than relative movement) to the guest OS, improving user experience without requiring guest additions.

  1. Right-click the Start button and select Device Manager.
  2. Expand Universal Serial Bus controllers.
  3. Look for "Unknown USB Device (Device Descriptor Request Failed)".
  4. Right-click it > Uninstall device.
  5. Unplug the USB device.
  6. Restart your computer.
  7. Plug the device back in after Windows fully loads.
  • If the device works on another PC: You have a driver issue. Fix it via Registry cleanup.
  • If it fails everywhere: You likely own a counterfeit or bricked device.
  • If you need the data: Seek professional recovery, but prepare for bad news.
  • If you just want a working drive: Run a Mass Production tool or buy a genuine drive from a reputable brand.
  • Capture the device descriptor using Wireshark with USBPcap or usbmon to see if it's trying to emulate a keyboard and inject keystrokes.
    1. CH340 / CH341 clone – WCH (Nanjing Qinheng Microelectronics) uses 0x1A86, but some counterfeit or incorrectly flashed clones fall back to FFFF:1201 when EEPROM is blank.
    2. PL2303 clone – Prolific’s official VID is 0x067B. Clones often use FFFF if the EEPROM is unprogrammed.
    3. FTDI clone – FTDI uses 0x0403. Again, knockoffs may default to FFFF.
    4. Custom microcontroller (e.g., STM32, LPC, or ATmega running firmware that incorrectly sets the VID).
    • Kernel module usbserial may bind with option vendor=0xffff product=0x1201.
    • Module ch341 sometimes binds if the device responds to CH341-specific commands.
    • dmesg output:
      usb 1-2: new full-speed USB device number X using xhci_hcd
      usb 1-2: Manufacturer: USB
      usbserial_generic 1-2:1.0: Generic device with no bulk out, not allowed.

    Rockchip

    The specific pairing of VID FFFF and PID 1201 is frequently observed in devices utilizing system-on-chip (SoC) architectures (e.g., RK3066, RK3188, RK3288, RK3399). usb device id vid ffff pid 1201
