Plug your problematic USB drive into a direct motherboard port (avoid external USB hubs). Open ChipGenius and locate your drive in the list. Scan the detailed text box for the following signatures: FirstChip Controller Part-Number: chipYC2019 (or FC1179 / FC1179S)
| Specification | Details | | ------------------------ | ------------------------------------------------------------- | | | FirstChip (一芯) | | Interface | USB 2.0 High‑Speed | | Common Designations | chipYC2019, FC1179, FC2279 (these are functionally identical) | | Flash Support | TLC, QLC, and other NAND types; often paired with SanDisk, Intel, or WDC chips | | Channel Configuration | Typically 1‑CE / Single Channel | | Detected ID | VID=FFFF, PID=1201 (common value) | | Compatible Tools | FirstChip MpTools series | firstchip+yc2019+new
Because these chips are heavily used in generic, budget, and promotional USB sticks, they frequently suffer from data corruption. Hardware degradation or unexpected power cuts can cause the controller to lose track of its firmware.
Inside the Settings window, find the tab to modify how the tool restructures the memory cells: Configuration Tab Parameter Name Recommended Value / Action Flash Setting Flash Name
在产品层面，高端U盘和SSD方案替换旧款FC1179的迭代正在进行中，新一代芯片已在官网与行业论坛被提前披露，量产工具随固件更新速度也逐年加快。 Flashing firmware completely wipes the drive's memory blocks
The is a NAND flash controller produced by FirstChip Technology Limited. It acts as the "brain" of the USB drive, managing data transmission between the NAND flash memory chips and the computer.
New scanning algorithms isolate unstable memory cells more efficiently, preventing subsequent corruption.
Standard Windows tools like Disk Management or diskpart cannot fix this because the problem is at the controller level. To bring your drive back to life, you need a specialized Mass Production Tool (MPTool). 🛠️ The FirstChip yc2019 Toolkit Scan the detailed text box for the following
Click the button on the right panel. When a password prompt appears, leave it blank and simply click OK . Step 4: Adjust Scan and Capacity Settings
Launch FCMpTools.exe by right-clicking and selecting . The program will initially boot with a Chinese user interface. Look at the top-right corner of the window, click the language dropdown menu, and select English to make the configuration panels readable. Accessing Advanced Settings
If the tool recognizes the drive, it will display the controller type.
If successful, FirstChip will have achieved what the EU Chips Act and the U.S. Department of Commerce have failed to do: bring true visibility to the most opaque supply chain on earth.
