Usb Device Id Vid 1e3d Pid 198a

Another driver (e.g., a mobile phone driver, virtual disk software, or older Chipsbank driver) may be hijacking the device. This is common after installing software like VMware, Daemon Tools, or certain Android USB debugging packages.

Some commercial environmental sensors (particulates, VOC, CO2) using a Chipsea MCU as a USB-to-sensor bridge may report this PID. For example:

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 VID_1E3D&PID_198A. This alphanumeric string looks intimidating, but it is simply the "fingerprint" of a specific USB device.

In the world of USB hardware, every device contains two critical identifiers: Another driver (e
