198A (Specifies the Generic Mass Storage/UDisk configuration )
If you have landed on this page, you are likely staring at your computer’s Device Manager, a cryptic error message, or a driver update tool that has flagged a piece of hardware with the identifier . This alphanumeric string looks intimidating, but it is simply the "fingerprint" of a specific USB device.
The USB device with and PID 198A is conclusively identified as a Chipolo Classic BLE tracker . It uses the USB connection exclusively for charging and does not provide any data transfer functionality. No further driver or software interaction is required or possible via the USB interface.
It's common to see a device identified simultaneously by lsusb in Linux as a Chipsbank Microelectronics Co., Ltd device, while its Windows properties list the manufacturer as ChipsBnk or Chipsailing . This discrepancy suggests that VID 1E3D is shared among related entities, but the primary application of PID 198A is for mass storage controllers. Usb Device Id Vid 1e3d Pid 198a
Users frequently search for this specific ID when their drive stops working or shows as unreadable. Common symptoms include the drive reporting 0MB capacity, asking to be formatted constantly, or failing to be recognized by Windows. 1. Quick Troubleshooting
In some ultrabooks and 2-in-1 devices, the touchpad PCB integrates a small fingerprint scanner in the top-left or top-right corner. The USB interface reports as a single composite device with two interfaces: one for the touchpad (HID mouse) and one for the fingerprint reader. In that case, VID_1E3D&PID_198A might represent the fingerprint portion.
: Users frequently report issues where the device is recognized by the OS but shows "No Media" or 0 bytes capacity, often after a failed formatting or bootable drive creation. Repair Tools It uses the USB connection exclusively for charging
The USB hardware identifiers correspond to a Flash Disk manufactured by Chipsbank Microelectronics Co., Ltd. DeviceHunt
The drive requires formatting but fails, citing errors like "Windows was unable to complete the format."
1E3D Product ID (PID): 198A
The corresponds to a ChipsBank-based USB flash disk. If it is not working, it is usually because the controller software needs to be re-flashed using specialized ChipsBank APTool utilities rather than standard Windows formatting tools.
| PID (hex) | Typical Device | | --------- | ------------------------------------- | | 0x1980 | CSU8RF718x Development Board | | 0x1985 | CS32G020 (USB Power Delivery MCU) | | | Generic DFU / Bridge (this entry) | | 0x1990 | CSU32M10 Touchpad Controller |
The CBM2099 controller stores its operating firmware in a serial flash or directly on the NAND. If you unplugged the drive during a write operation, the firmware can become corrupted. The USB stack will still read the VID/PID from the controller’s ROM, but the device will appear as “Removable Device” without a drive letter. This discrepancy suggests that VID 1E3D is shared
