Unlike a printer or graphics card, a USB flash drive does not require a driver from the manufacturer to read/write data. However, when the firmware on the FC1178BC controller becomes corrupted (due to unsafe ejection, power loss, or bad blocks), Windows cannot communicate with it properly.
Your symptoms will look like this:
To fix this, you must bypass the standard Windows storage driver and use a FirstChip mass production tool that speaks directly to the FC1178BC controller.
The FC1178BC is a USB 2.0 flash controller chip manufactured by FirstChip. It is commonly found in budget "no-name" USB flash drives, promotional thumb drives, and low-cost electronics. firstchip fc1178bc download
Because it is a programmable controller, it is often the subject of counterfeiters who use it to make small capacity drives look like large ones (e.g., selling a 1GB drive as a 128GB drive). Consequently, the "download" most people look for is the MPTools (Mass Production Tools) software designed to reprogram these chips.
Unlike older SMI controllers, FirstChip tools are portable but picky:

Most量产工具 (mass production tools) auto-detect chips. The FC1178BC is notorious for being misreported as an FC1179 or generic 1178.

No. Do not attempt. Using the wrong MP tool can physically short the controller. You need the tool specifically for FC1178BC. To fix this, you must bypass the standard
Before downloading, you must identify your exact controller. FirstChip has released several iterations:
| Controller | Typical Use | MP Tool Compatibility | | :--- | :--- | :--- | | FC1178 | Early USB 2.0/3.0 drives | Older tools (pre-2019) | | FC1178BB | 64GB–128GB TLC NAND | Specific "BB" tools | | FC1178BC | 128GB–256GB QLC/3D TLC | Latest tools (v1.0.3.6+) |
The FC1178BC is the most recent and picky. Using an older tool designed for the FC1178 will result in a "Device Not Matched" error.
