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:
macOS often refuses to mount Chipsbank-based drives, especially those with invalid partition tables. To fix:
If you discovered this hardware ID while checking a newly purchased 2TB or 16TB external SSD or flash drive bought at an impossibly low price, you are likely dealing with a spoofed or counterfeit storage device. Usb Device Id Vid 1e3d Pid 198a
Devices carrying this specific VID/PID combination are built using structural components that define their speed limits, power draws, and operational limits.
This ID usually represents a ChipsBank-based Flash Disk or Flash Drive. The device VID:1E3D PID:198A does function as a
Some commercial environmental sensors (particulates, VOC, CO2) using a Chipsea MCU as a USB-to-sensor bridge may report this PID. For example:
Before attempting complex firmware overwrites, verify basic functionality: USB Flash Drive Speed Tests - VID = 1e3d, PID = 198a Devices carrying this specific VID/PID combination are built
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.
: USB 2.0 High Speed (backwards compatible with USB 1.1). Power Usage : Max current is generally around 100mA . Performance Review
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.
