Vid 346d Pid 5678

When a flash drive enters this state, consumer-grade data recovery software (like Recuva or EaseUS) will not work because the computer cannot access the memory NAND blocks. Recovering data from a device stuck in this hardware state requires professional data recovery services capable of unsoldering the memory chip and reading it via specialized hardware.

Having the correct VID and PID is incredibly useful if your computer is failing to recognize your USB drive. If your Teamgroup C222 is not showing up or is throwing an error, use these identifiers to resolve the issue:

USB Flash Drive Speed Tests - VID = 346d, PID = 5678 - NirSoft

Many white-label devices use chips from mainstream manufacturers like FTDI, Prolific, CH340, or Silicon Labs, but use a modified VID/PID. If you know the underlying chipset, you can force the installation of that manufacturer's standard driver using the "Let me pick from a list of available drivers on my computer" option in Device Manager.

The most frequent cause is that Windows lacks the specific driver needed to translate commands for this specific Beijing Jinchangshu hardware. Without the proper driver, Windows drops back to reading the raw hardware ID. 2. Firmware Corruption (The "Default ID" Phenonmenon)

Performance varies significantly. Tests on USB Speed (NirSoft) show sequential read speeds around 19 MB/s and write speeds near 6.5 MB/s for 32GB models.

Expand the or look under Disk drives . Right-click your USB drive and select Properties . Navigate to the Details tab. Under the Property dropdown menu, select Hardware Ids . You will see a value string containing VID_346d&PID_5678 .

Usually powered by the FirstChip controller (specifically models like FC1178 , FC1178BC , or FC1179 ) ⚠️ Important Warning: Fake Capacity

If your device is failing to work, dropping connections, or showing up as an "Unknown Device," follow these troubleshooting steps to restore functionality. Step 1: Fix Driver Issues

Devices with these IDs are often generic or "white-label" drives. Users have reported the following:

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 One user’s trash becomes another’s firmware snapshot, which becomes an archived page in a wiki. If your Teamgroup C222 is not showing up

The standard Windows formatting utility will fail. You must use chip-level recovery software. Downloading FirstChip MpTools allows you to execute a low-level factory reset on the controller. 2. Fake Capacity Discrepancies

This paper provides a technical overview of the hardware device identifying as Vendor ID (VID) 346D Product ID (PID) 5678

Some unscrupulous online vendors flash mass-produced VID 346D boards with modified firmware that reports an artificially high storage limit (e.g., listing 2TB when the actual internal flash chip only holds 1GB or 16GB).

Using MPTools will wipe all data on the drive and can permanently brick the device if the wrong settings are applied.

Because these drives use the FirstChip controller, they are often recoverable if they become corrupted or show "Write Protected" errors.

If you see this, the USB drive is likely experiencing firmware issues, allowing it to connect but preventing it from being accessed, formatted, or showing the correct capacity.
