USB Vendor IDs are not random. Google’s other VIDs include:

The number 1949 is believed to reference the founding year of the People’s Republic of China – a coincidence or a deliberate nod to manufacturing partners? No official statement exists. However, PID 0402 is unequivocally the Stadia Controller’s first USB profile.

The minus signs in your keyword string are advanced operators:

Thus, Google interprets this as:
gamepad "1949" "0402" but without common e-commerce or spec-sheet words.

This is a high-intent technical query – someone has already identified the device via lsusb and wants documentation, drivers, or fixes, not a store page. If you’re reading this, you probably already own the controller and want to make it work on a non-mainstream OS.

The gamepad -vendor 1949 product 0402- is a fascinating piece of hardware anthropology. It represents the massive, grey-market OEM industry of Shenzhen. It is not a premium device. It is not a hidden eSports weapon. It is a simple, functional, and frustratingly generic PlayStation 2 clone that has been plugged into millions of PCs for two decades.

If you see this string in your system, you now know: You are holding a "SainSonic" or "Shenzhen Saidian" reference controller. It will work for classic emulation out of the box. For modern gaming, you will need x360ce. And if it breaks, do not repair it – simply buy a modern controller with official XInput support.

Treat VID 1949 PID 0402 as what it is: a humble workhorse of the budget gaming stable, not a thoroughbred.

Understanding the hardware signature Vendor 1949, Product 0402 is essential for gamers attempting to repurpose older hardware for modern PC or Linux setups. This specific identifier belongs to the 1st Generation Amazon Fire TV Game Controller.

Produced by Lab126 (Amazon’s hardware R&D arm), this controller was originally designed to pair with the 2014-era Fire TV. While it was innovative for its time, using it on non-Amazon devices today requires specific mapping and driver configurations. Hardware Profile: Amazon Fire TV Controller (Gen 1)

The "1949:0402" model is a Bluetooth-based gamepad that mimics the ergonomics of an Xbox 360 controller.

Connectivity: Primarily Bluetooth (3.0 or Wi-Fi Direct depending on the specific firmware version).

Power: Requires two AA batteries; it is not internally rechargeable.

Input Layout: Features dual clickable analog sticks (L3/R3), analog triggers (L2/R2), and dedicated media controls (Play/Pause, Forward, Rewind) at the bottom. Unique ID: Vendor ID (VID): 1949 (Lab126 / Amazon) Product ID (PID): 0402 (1st Gen Gamepad) Usage on Windows and Linux

Because this controller was built for a closed ecosystem, modern operating systems often misidentify its inputs. 1. Linux & RetroPie Issues

In Linux environments (such as Ubuntu or RetroPie), the device is frequently detected as a "Gamepad Keyboard" or "Consumer Control" rather than a standard joystick.

D-Pad Conflict: The most common issue is the D-pad being treated as an axis (often Axis 9) instead of digital buttons.

Fix: You may need to create a custom udev rule to force the system to recognize it as a joystick. Use a command like nano /etc/udev/rules.d/99-amazon.rules and add:SUBSYSTEM=="input", ATTRSname=="Gamepad", ENVID_INPUT_JOYSTICK="1". 2. Windows Mapping

Windows 10 and 11 will generally pair with the device via Bluetooth, but games may not see it as an XInput device. Bluetooth controllers are not working - CoreELEC Forums

The hardware identifier Vendor 1949, Product 0402 refers to a generic Bluetooth game controller often associated with brands like iPEGA (specifically the PG-9118) or unbranded "N1-3017" mobile gamepads. While the vendor ID 1949 is officially registered to Lab126 (an Amazon subsidiary), it is frequently used by these third-party gamepads when operating in certain Bluetooth HID (Human Interface Device) modes. Device Overview and Identification

When connected to a system—particularly Linux-based environments like RetroPie, Lakka, or Ubuntu—the device typically presents itself with the following characteristics:

Name: Often appears as "Gamepad," "Gamepad Keyboard," or "Gamepad Mouse" depending on the selected pairing mode.

Pairing Modes: These controllers usually support multiple modes (e.g., Android, iOS, or PC/HID) triggered by holding specific button combinations (like Home + A or Home + X) during power-on.

Internal Hardware: Some users report these devices are generic "knock-offs" designed primarily for mobile use but compatible with PC and single-board computers via standard Bluetooth stacks. Common Technical Issues

Users frequently encounter challenges when integrating this specific hardware ID into gaming setups:

Initialization Failures: On some Linux distributions, the controller may pair and connect but fail to initialize properly, leading to "No controllers detected" errors in software like Steam.

D-Pad Remapping: Technical reports on platforms like GitHub indicate that the D-pads on these 1949:0402 devices may not be remappable via standard Gamepad APIs in certain game engines.

Multiple Input Profiles: The device may simultaneously register as a keyboard, mouse, and consumer control device, which can confuse emulator software that expects a single joystick input. Troubleshooting and Setup Guide

The hardware identification (Vendor ID: 1949, Product ID: 0402) is a common "signature" for various Bluetooth gamepads, most notably the Amazon Fire Game Controller

. Interestingly, this ID is also frequently used by third-party manufacturers, particularly , to ensure compatibility with Android and other platforms. Device Identification & Variants Devices reporting as

often appear under different brand names due to shared firmware or "Android mode" emulation: Amazon Fire Game Controller : The primary owner of the Vendor ID (registered to Lab126, Inc. , Amazon's hardware division). Ipega PG-9069

When connected to a computer or console, the system typically sees multiple "handlers" because these controllers often mimic several input types at once:

The hardware ID 1949:0402 refers to the Amazon Luna Controller and its predecessor, the Amazon Fire Game Controller. It is frequently encountered in Linux and Windows environments when configuring gamepads via Bluetooth or USB. Device Specifications Vendor ID (1949): Amazon.com.

Product ID (0402): Specifically identifies the Luna Wireless Controller or Fire TV Game Controller.

Alternative Manufacturers: Some generic controllers (e.g., Ipega PG-9069 or GameSir T4 Pro in Android mode) intentionally mimic this ID to ensure compatibility with standard drivers. Usage & Setup This controller supports three primary connection methods:

It looks like you’re referencing a USB vendor/product ID pair:
vendor 1949 = Google Inc.
product 0402 = Stadia Controller (in USB mode)
