| Component | Code | Meaning & Technical Details | | :--- | :--- | :--- | | | HID | Human Interface Device . This top-level descriptor tells Windows the device is used for human input, like a keyboard, mouse, or game controller. This allows the system to apply a standard set of HID drivers, which handle basic functionality like key presses and pointer movement. | | VID | 1EA7 | Vendor ID . This 4-character hexadecimal code is the manufacturer's unique identifier, assigned by the USB-IF. For a VID code (here in lowercase), you can see it corresponds to SEMITEK INTERNATIONAL (HK) HOLDING LTD. , but for its devices, it is used by SHARKOON Technologies GmbH . | | PID | 0066 | Product ID . This 4-character hexadecimal code is assigned by the manufacturer to a specific product model. Combined with the VID, it uniquely identifies the device. This PID corresponds to a 2.4GHz wireless combo device . It's often attached to a wireless dongle supporting a mini keyboard and mouse. | | REV | 0200 | Revision Number . This hexadecimal number indicates the hardware or firmware version of your specific device. It could be a batch number or a manufacturing revision. | | MI | 00 | Multiple Interface . The MI_00 signifies this device is a "composite device" with multiple functions (keyboard and mouse). The 00 indicates it's the first interface (often the keyboard). The mouse is typically on MI_01 . |
Because the device adheres to HID standards, you can use:
pnputil /delete-driver oem*.inf (after locating the right INF) pnputil /scan-devices If the device shows up as "Unknown Device"
(often associated with SHARKOON or similar peripheral manufacturers). : This is the Product ID . In this context, it often corresponds to a Wireless Optical Mouse or a similar input device. : The revision number of the hardware (Version 2.0). : Refers to the "Multiple Interface" index.
The hardware identification string points directly to a specific composite USB Human Interface Device (HID) manufactured by SHARKOON Technologies GmbH (or distributed under brands like Plexgear). Specifically, this hardware ID corresponds to a wireless receiver dongle or direct interface for a media keyboard, often listed in hardware repositories as the Mediatrack Edge Mini Keyboard .
When you see this string in your Device Manager or system logs, your computer is recognizing a SHARKOON-manufactured peripheral. Because it is an HID-compliant device, it typically uses standard "Plug and Play" drivers provided by the operating system, meaning you generally do not need to download external software to make it work. Common Uses Driver Troubleshooting
The hardware ID HID_VID_1EA7&PID_0066&REV_0200&MI_00 identifies a generic 2.4GHz wireless combo device—typically a keyboard and mouse set sold under various brand names like SHARKOON Mediatrack Edge Mini or as individual mice like the HXSJ M103. While these devices work adequately for basic computing tasks on most operating systems, they may present compatibility issues, particularly with Linux, and lack advanced features found in more expensive peripherals. According to device databases DeviceHunt , the vendor
