, a semiconductor company based in Shenzhen, China. They specialize in low-cost flash memory controllers, which are the "brains" of a USB drive that manage how data is stored and retrieved. The Device Identity Product ID (PID) 198A : This specific ID is typically assigned to their "HighSpeed" or generic "Flash Disk" Common Use
Ensure the scanned Flash ID automatically matches the physical silicon reported by ChipGenius in Step 1.
198A (Commonly assigned to Flash Disks and Flash Readers) Device Type: USB 2.0 Mass Storage Device Common Controllers: CBM2098, CBM2099E, CBM2199S 🛠️ Common Use Cases & Behavior Usb Device Id Vid 1e3d Pid 198a
Note the specific (e.g., CBM2199E) and the Flash ID / Flash Part Number (the underlying memory chips built by Samsung, SanDisk, Hynix, or Toshiba). Step 2: Source the Target Flashing Utility
Operating systems read basic configuration properties encoded directly inside the silicon microcode to identify a peripheral when it is plugged into a USB port. For this specific device, the operational metadata exposes the following structural details: , a semiconductor company based in Shenzhen, China
macOS often refuses to mount Chipsbank-based drives, especially those with invalid partition tables. To fix:
The device VID:1E3D PID:198A does function as a standard mass storage, audio, or HID peripheral. Instead, it is typically encountered in one of three operational contexts: 198A (Commonly assigned to Flash Disks and Flash
: Often categorized as entry-level storage, frequently appearing in speed tests for "Generic Flash Disk" devices. Common Troubleshooting Scenarios
For the most serious issues, only software used at the factory will work. This is where the comprehensive information from the VID/PID becomes invaluable, as it tells you which tool is compatible. These powerful tools, commonly referred to as "量产工具" (mass production tools), can perform low-level formatting and re-flash the controller's firmware.
Download this free utility first to query the drive. It will read the internal registers and tell you the exact Chipsbank controller part number (e.g., CBM2099E).
