Usb Vid-214b Amp-pid-7250 Amp-rev-0100 <2K 2027>

Electron Executor is a Level 8 Windows executor known for having one of the fastest post-patch update turnarounds in the executor community. When Roblox pushes an update, the Electron team has a compatibility patch live within an hour in most cases. Keyless access, a 2,500-script hub, and a clean interface round out an executor that prioritizes availability and reliability over experimental features.

Vendor ID (VID): 0x214B
Product ID (PID): 0x7250
Revision: 0100

Follow these methods in order. You likely do not need to download any sketchy "driver updater" software.

If you were writing a driver configuration file, the matching line would look like this:

[WD.NTamd64]
%USB\VID_214B&PID_7250.DeviceDesc% = USBSTOR, USB\VID_214B&PID_7250

[Strings]
USB\VID_214B&PID_7250.DeviceDesc = "Western Digital External Hard Drive"

Title: Decoding the Hardware Identity: A Deep Dive into USB VID 214B & PID 7250

Introduction

In the complex ecosystem of Universal Serial Bus (USB) devices, every piece of hardware speaks a specific digital language. While users interact with friendly device names like "Wireless Mouse" or "Flash Drive," the computer’s operating system sees something far more precise: a set of numerical codes. Among these, the combination of VID-214B and PID-7250 (with a revision of 0100) represents a specific fingerprint in the vast hardware database.

This article explores the technical significance of these identifiers, how to interpret them, and why they matter for troubleshooting and hardware compatibility.

The USB identifier VID_214B&PID_7250&REV_0100 points to a Huaxu Electronics USB 2.0 bridge chip – 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. Vendor ID (VID): 0x214B Product ID (PID): 0x7250

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.

If you still need assistance, post in the r/techsupport subreddit with the exact text: "Device Manager shows USB\VID_214B&PID_7250&REV_0100 – tried forced driver, no luck." Include your Windows version and the physical device model.

. 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: Content for: A Western Digital external hard drive

Indicates the specific firmware or hardware version of the controller. Raspberry Pi Forums Common Products Using This ID

This internal chip is found in various unbranded and branded USB accessories, including: AIMOS AM-UK404: A 4-port USB 2.0 KVM switch. GINZZU GR-315UB: A standalone 4-port USB hub. Embedded Hubs: Often found inside larger devices like all-in-one PCs (such as HP or ASUS series), or display docks that provide additional USB ports. Driver Information Because this is a standard USB Hub, it is "plug-and-play"

and does not require proprietary drivers. It uses the generic Windows "Generic USB Hub" usbhub.sys

) or standard Linux hub drivers. If the device is not working: Power Cycle:

Unplug the hub and the computer from power briefly to reset the controller. Device Manager:

  • Inspect descriptors to determine:
  • Check product strings (iManufacturer, iProduct, iSerial) for vendor/model names.
  • If device exposes vendor-specific interface, try to find an open-source driver or reverse-engineer control messages using usbmon (Linux) or Wireshark with USB capture.
  • Look for firmware update endpoints or DFU mode (interface with DFU class or vendor-specific flashing commands).

    • A: Absolutely not. There is no official signed driver from Huaxu for this chip because Microsoft includes the driver already. Driver download sites often bundle adware or ransomware. Uninstall any such software immediately.
