After applying Method 1 or Method 2 above, 95% of users will see their device transform into a working CD-ROM or disk drive. For the remaining 5%, the REV-0100 hardware has likely reached the end of its functional life.
When this device fails to install, it will appear in the Windows Device Manager under "Other Devices" with a yellow exclamation mark, often labeled as "Unknown Device" or "USB 2.0 Hub."
: It often appears in generic 4-port expansion hubs like those from GINZZU (specifically the GR-315UB model).
The USB device with the identifier VID_214B&PID_7250&REV_0100 is a specific hardware component that connects to a computer via the Universal Serial Bus (USB). This device, like others, is identified by a unique combination of its Vendor ID (VID), Product ID (PID), and Revision (REV). Understanding the specifics of this device requires analyzing these identifiers and relating them to the device's functionality and compatibility. usb vid-214b amp-pid-7250 amp-rev-0100
The typical user experience is uneventful, which is exactly what you want from a hub: it just works. The only notable limitation is that . While this is fine for keyboards, mice, printers, and low‑end flash drives, it will be a bottleneck for external SSDs or high‑resolution webcams that require USB 3.0 (or higher) bandwidth.
Want to confirm that you have this device on your own computer? Here’s how:
Often found as an internal hub in laptops (e.g., HP 15-db1xxx) or on desktop motherboards to manage front-panel ports. Driver & Compatibility After applying Method 1 or Method 2 above,
. Specifically, this Hardware ID is often associated with the HS8836A 4-port Hub chip Device Identification Vendor ID (VID) 214B: Associated with Huayi/Asix or generic Chinese USB controller manufacturers. Product ID (PID) 7250: Typically identifies a high-speed USB 2.0 hub controller Revision (REV) 0100:
For most modern operating systems, including , no manual driver download is required.
Help identifying USB device – VID_214B PID_7250 REV_0100 The typical user experience is uneventful, which is
The USB identifier VID_214B&PID_7250&REV_0100 points to a – most likely inside an external DVD writer or hard drive enclosure. The solution is rarely finding a specific driver; it is about fixing Windows' driver assignment, removing conflicting legacy filters, or updating the firmware.
While specific technical specifications can't be derived directly from the VID, PID, and REV alone, we can infer some general characteristics based on SiFive's product portfolio:
– This ID belongs to Huasheng Electronics . They are a common manufacturer of low-power USB controller chips used in a wide variety of generic and brand-name electronics.
Identifies the manufacturer. VID 214B is generally associated with Generic USB Hubs or specific white-label USB audio/connector manufacturers, often found in HP or other laptop internal assemblies.
