Vid 346d Pid 5678 -
A four-digit hexadecimal number assigned by the USB Implementers Forum (USB-IF) to identify the manufacturer.
Every USB device contains hardcoded identification strings that tell the operating system what it is and who manufactured it.
If your device is suddenly showing up as VID 346D PID 5678 and failing to work, the root cause usually falls into one of three categories: 1. Missing or Corrupted Drivers
Because these IDs are frequently used by generic manufacturers, you will often find them in: vid 346d pid 5678
. This specific hardware profile is associated with budget-tier, highly compact "chip-on-board" USB 2.0 flash drives. This document outlines the hardware specifications, performance benchmarks, and deployment use cases for system administrators and hardware forensic analysts. 1. Hardware Identification
This Vendor ID corresponds to WCH (Nanjing Qinheng Microelectronics Co., Ltd.) . WCH is a prominent manufacturer known for producing USB-to-serial chips, interface ICs, and microcontrollers.
That’s how communities turn orphaned identifiers into living histories. One user’s trash becomes another’s firmware snapshot, which becomes an archived page in a wiki. A four-digit hexadecimal number assigned by the USB
Reports from NirSoft's USB Speed Test database and user forums indicate the following real-world speeds: Approximately 15–20 MB/s . Average Write Speed: Approximately 4–7 MB/s .
Typically relies on the FirstChip FC1178BC or FirstChip FC2279 microcontroller family.
The software should detect the device as VID 346D PID 5678 or VID FFFF PID 1201 . Missing or Corrupted Drivers Because these IDs are
The USB-IF maintains strict control over VID allocation, charging a fee to prevent chaos. Legitimate manufacturers receive a unique VID and then freely assign PIDs within their range. For example, if 0x346d were a valid VID, the company could assign 0x5678 to a webcam, 0x5679 to a fingerprint reader, and so on. This hierarchical structure ensures that two different companies never accidentally use the same pair.
