Vid 346d Pid 5678 Best Verified Upd -

The hardware identifiers VID 346D and PID 5678 are associated with Shenzhen SanDiYiXin Electronic Co., LTD, a manufacturer of various USB flash drives. These IDs are often found on generic or rebranded "white-label" devices like those from VendorCo, Dahua, Eaget, or Hiksemi.

Identify the Chipset: Use ChipGenius to get a deeper look at the specific Controller Vendor and Flash ID. If you are having trouble with this device, let me know: Is the drive not showing up at all? Are you getting a "write protected" error?

Controller: Frequently uses the FirstChip FC1178BC or similar controllers. Protocol: Standard USB 2.0 interface. vid 346d pid 5678 best verified

Reported Performance: Users have noted extremely poor "small block" (random) read/write speeds, often as low as 0.7 MB/s. Technical Context & Recovery

Note on Data Verification: In standard hardware databases, VID 346D is typically associated with Radio Shack (or Tandy Corporation). However, the specific PID 5678 does not appear in common public driver repositories as a standard commercial product. This suggests the device is either a generic OEM device, a microcontroller development board (like an Arduino clone using a specific USB chip), or the PID is used for internal testing/verification purposes.
