Usb Device Id Vid Ffff Pid 1201

While the device is likely a legitimate piece of hardware in a development or recovery state, the following security considerations apply:

For digital forensics and incident response (DFIR), finding VID_FFFF:PID_1201 in USB connection logs (e.g., Windows SetupAPI.dev.log, Linux /var/log/syslog, or USB forensic artifacts like SYSTEM\CurrentControlSet\Enum\USB) is a high-priority alert if the host is not a VM.

This document explains what a USB device ID is, how to interpret VID and PID values, and specifically covers the case of a device reporting VID = 0xffff and PID = 0x1201. It includes likely causes, diagnostic steps, OS-specific behavior, driver implications, security considerations, and troubleshooting/repair guidance. usb device id vid ffff pid 1201

Multiple sources (Linux lsusb database, Windows driver logs, open-source hardware repositories) consistently map VID_FFFF&PID_1201 to:

| 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 | While the device is likely a legitimate piece

The USB device with ID FFFF:1201 is not a standard consumer product. It is highly probable that this is a Rockchip-based device in Mask ROM/Recovery Mode or a microcontroller development board with unprogrammed descriptors.

Recommendation: Treat the device as a technical engineering tool. If this device appeared unexpectedly in a corporate environment, it should be treated with suspicion as it does not conform to standard hardware compliance profiles. For digital forensics and incident response (DFIR), finding

While no major commercial vendor sells products with VID FFFF, forensic analysis of open-source drivers and firmware repositories links this ID pair to specific hardware scenarios:
