Right-click the problem device in Device Manager and select . Choose Browse my computer for drivers .
These devices frequently use controllers from FirstChip (such as the FC1178BC) or ChipsBank . Common Characteristics
If the device is a programming tool, open the associated flashing software (like STM32CubeProg, Arduino IDE, or specific radio tools) first; these programs usually bundle the necessary backend drivers inside their installation directories.
A four-digit hexadecimal number assigned by the manufacturer to identify the specific product model.
If VID 346D PID 5678 were a real device, the article would include: vid 346d pid 5678
A four-digit hexadecimal number assigned by the USB Implementers Forum (USB-IF) to identify the manufacturer.
The pair signifies a device manufactured by WCH (Nanjing Qinheng Microelectronics) , likely a CH34x USB-to-Serial converter . Identifying this allows for precise troubleshooting and quick resolution of driver-related connectivity issues.

You can check a USB drive's VID and PID yourself. Here is how to see if your device matches 346d:5678 . Right-click the problem device in Device Manager and select
Using these tools will erase all data on the drive. You can find these specialized recovery utilities on community sites like USBDev.ru or FlashBoot.ru . 2. Windows Driver Troubleshooting If the hardware is healthy but the system won't mount it: VID = 346d, PID = 5678 - USB 3.0 Flash Drive Speed Tests USB 3.0 Flash Drive Speed Tests - VID = 346d, PID = 5678.
Here are a few possible interpretations or actions based on this information:
The USB hardware identifier refers to a generic USB Flash Drive often marketed under names like "Disk 2.0" or "VendorCo ProductCode" . These identifiers are most frequently associated with budget or promotional flash drives that use FirstChip controllers (specifically the FC1178BC or FC2279 models). 1. Identifying the Hardware
(Typically represents generic or outsourced solid-state storage fabricators). Product ID (PID): (Associated with the "USB Disk 2.0" product line). Device Class: Mass Storage Device. Form Factor: Common Characteristics If the device is a programming
If multiple devices with the same VID and PID are connected to a computer, conflicts can arise.
Because the "VID 346D PID 5678" error means the controller firmware is corrupted, standard formatting tools like Windows Disk Management or Rufus will not work. You must re-flash the controller using a specialized production utility.
For drives using the FirstChip controller, specialized low-level formatting tools like ChipGenius or FirstChip’s proprietary recovery utilities are often used to reset the firmware.
