Vid 346d Pid 5678

This is because of . Shenzhen Feitian sells the hardware to a reseller. The reseller puts their logo on the plastic casing but provides their own drivers. Feitian often does not host drivers for these specific PIDs on their own public website because they expect the reseller to handle support.

Once you have identified the controller chip, you must use the correct FirstChip MpTools version.

Every USB device plugged into a computer communicates using two standard 16-bit hex identifiers so the operating system knows which driver to load:

When these drives properly negotiate a SuperSpeed USB 3.0 connection, they are capable of significantly better performance. One such drive, the , recorded a Write Speed of 9.68 MB/s and a Read Speed of 34.86 MB/s when tested. vid 346d pid 5678

A user-friendly interface provides device information, status updates, and easy access to device management features.

Before diving into this specific code, it's crucial to understand what the terms VID and PID mean. These are not random numbers but standardized identifiers used in universal serial bus (USB) technology.

: Typically FirstChip (models like FC1178BC or FC3379BB). This is because of

Users have reported a slight performance increase (up to 19 MB/s read) when formatting the drive with the exFAT file system instead of the default FAT32. Maintenance and Repair

When troubleshooting hardware issues or developing embedded systems, you often encounter cryptic alphanumeric identifiers in your operating system's device manager. One such identifier is . Every USB device plugs into a computer with these hidden strings of code. They tell the host operating system exactly what the hardware is and which driver to load.

: Usually listed as VendorCo or simply USB . Feitian often does not host drivers for these

Open a terminal and use the powerful lsusb command. To specifically check for this ID, you can filter the output: $ lsusb -d 346d:5678 If the device is connected, you will see an entry similar to: Bus 001 Device 002: ID 346d:5678 USB Disk 2.0

Because many generic or promotional USB drives share this identification profile, users frequently run into systemic bugs. 1. Drive Shows "Write Protected" or Read-Only Mode

If you are "preparing a paper" on this device—likely for a technical report, performance log, or documentation—here is the essential data to include: Device Specifications Vendor ID (VID): (Typically linked to or generic Chinese manufacturers) Product ID (PID): (Standard generic product code) Controller: Often identified as FirstChip FC1178BC USB 2.0 (High Speed) Standard Performance: Read Speeds: 10–25 MB/s Write Speeds: 3–10 MB/s Performance Optimization

Often listed as VendorCo ProductCode or Disk 2.0 . USB Protocol: USB 2.0 (High Speed). Power Consumption: 100mA.

This article provides a comprehensive guide to understanding this device ID pair, troubleshooting issues, and finding the correct tools to repair or recover a FirstChip-based drive, often referred to as "VendorCo" or "Generic" drives. What is VID 346D PID 5678?
