Device Id Vid 1e3d Pid 198a: Usb

Feature Title: Hardware Identification Profile: USB\VID_1E3D&PID_198A

Overview The USB device identifier VID_1E3D PID_198A refers to a specific piece of hardware commonly found in automotive diagnostic and telematics applications.

• Vendor ID (VID): 1E3D (Assigned to Audiophile Electronics Ltd)
• Product ID (PID): 198A

Primary Device Association This specific ID is overwhelmingly associated with the VAS 6154A diagnostic interface.

Device Specifications & Features

• Device Type: Vehicle Communication Interface (VCI)
• Primary Use Case: Official diagnostics and flashing for the Volkswagen Group (VW, Audi, Seat, Skoda, Bentley, Lamborghini).
• Connectivity:
  • Wireless: Integrated Wi-Fi (802.11 b/g/n) for remote diagnostics.
  • Wired: USB 2.0 connection for stable power and data transfer.
• Protocol Support: Supports all major OBD-II protocols as well as manufacturer-specific protocols (CAN, K-Line, UDS) used in modern VW Group vehicles.
• Software Compatibility: Designed for use with the ODIS (Offboard Diagnostic Information System) engineering and service software.

Technical Context The device appears to the host computer as a composite USB device. When connected via USB, it typically loads drivers that bridge the connection to the diagnostic software. While the device supports wireless operation, the USB connection (identified by this VID/PID) is often used for firmware updates or in environments where radio interference is a concern.

Troubleshooting & Drivers If this device appears as an "Unknown Device" in Windows Device Manager:

1. Driver Requirement: It requires the specific VAS 6154A drivers usually packaged with the ODIS software suite or the VW Group diagnostic toolkit.
2. Clone Warning: There are many aftermarket "clones" of the VAS 6154A hardware. While authentic units use this VID/PID, some lower-quality clones may spoof this ID or use different IDs entirely, which can lead to driver conflicts or firmware brick risks.

Summary If you see VID_1E3D PID_198A in your device logs, you are connecting an official or high-quality replica of the VAS 6154A, a professional-grade tool used by dealership technicians to service Volkswagen Group automobiles. Usb Device Id Vid 1e3d Pid 198a

Step 3: Update or Roll Back the Driver Manually

If automatic reinstallation fails, point Windows to the correct driver:

1. In Device Manager, right-click the device → Update driver.
2. Select Browse my computer for drivers.
3. Choose Let me pick from a list of available drivers on my computer.
4. Select USB Mass Storage Device (not the vendor-specific one).
5. Click Next and ignore any compatibility warnings.

7. Common Use Cases

1. Firmware update of a Chipsea-based embedded product (e.g., smart thermostat, gaming keyboard, industrial sensor).
2. In-circuit debugging/programming of CSU/CS32 MCUs during manufacturing or prototyping.
3. Data logging from a custom USB sensor module built around a Chipsea MCU.

Step 2: Uninstall and Reinstall the Device in Device Manager

1. Press Win + X and select Device Manager.
2. Scroll down to Universal Serial Bus controllers.
3. Look for any entry with a yellow exclamation, especially “Unknown USB Device” or “Mass Storage Device.”
4. Right-click the problematic device and select Uninstall device.
5. In the confirmation dialog, check “Delete the driver software for this device” (if available).
6. After uninstall, click Action > Scan for hardware changes.
7. Windows will attempt to reinstall the generic USB mass-storage driver.

1. Executive Summary

The USB Vendor ID (VID) 1E3D is registered to Chipsea Technologies (Shenzhen) Corp., also known as Chipsea Technologies. Chipsea is a Chinese fabless semiconductor company specializing in high-precision analog-to-digital converters (ADCs), touch controllers, biometric sensors, and battery management ICs.

The Product ID (PID) 198A falls within a range of devices typically associated with embedded microcontroller units (MCUs) or capacitive touch/temperature sensor interfaces. However, based on aggregated driver logs and hardware databases, this specific PID is most commonly identified as: Vendor ID (VID): 1E3D (Assigned to Audiophile Electronics

Chipsea CSU38F20 / CS32 Series Microcontroller in Firmware Update (DFU) Mode or a USB-to-SPI/I2C Bridge Tool.

Note: Unlike consumer peripherals (mice, keyboards), this VID/PID combination often appears when connecting a development board, a smart sensor module (e.g., air quality or temperature), or a device in bootloader mode.

5. Hardware Failure (Bad Capacitor or Crystal Oscillator)

The 12 MHz or 24 MHz crystal oscillator on the flash drive’s PCB may drift off frequency. In this case, the USB host controller can still read the basic VID/PID (low-speed negotiation), but high-speed mass-storage mode fails. but high-speed mass-storage mode fails.
