Short identification

  • Vendor ID (VID): 214B
  • Product ID (PID): 7250
  • Device revision: 0100

Security / Malware Notes

Because this VID/PID pair is common in cheap, unbranded flash drives, they are sometimes used in BadUSB attacks or preloaded with malware. Always scan the device before use.

The USB device with VID 214B, PID 7250, and REV 0100 is identified as a Huasheng Electronics USB 2.0 Hub. This hardware ID typically belongs to generic high-speed USB hubs often found in laptops (such as ASUS and HP models) or as standalone powered hubs. Device Details Vendor ID (VID) 214B: Registered to Huasheng Electronics.

Product ID (PID) 7250: Specifies the device as a USB 2.0 Hub.

Revision (REV) 0100: Indicates the firmware version is 1.00. Device Type: Generic High-Speed USB Hub. Driver Information

Because this device is a standard USB Hub, it does not require specialized third-party drivers on modern operating systems like Windows 7, 10, 11, or Linux.

Windows: Uses the native Generic USB Hub driver (usbhub.sys) provided by Microsoft.

Linux: Recognized natively by the xhci_hcd or ehci_hcd kernel modules as a "New high-speed USB device".

Update Method: If the device is not working, it is best to update via Windows Update or check your computer manufacturer’s support site, such as HP Support or ASUS Support, for chipset driver updates. Troubleshooting

If your system shows this device with a yellow exclamation mark or as an "Unknown Device," try these steps:

Title: Help identifying USB device – VID_214B PID_7250 REV_0100

Post:

I’m trying to identify a USB device that shows up in my system with the following identifiers:
VID_214B
PID_7250
REV_0100

VID 214B is known to belong to HuawaiWei (or a generic USB bridge controller), but this specific PID doesn’t match common Huawei modems. Some digging suggests it could be:

  • A USB to UART bridge (possibly CH340-like clone)
  • An external storage adapter (SD card reader)
  • A firmware update mode for a microcontroller board (Arduino clone, ESP, or similar)

What I’ve tried so far:

  • Checked Windows Device Manager → shows as “Unknown Device” with error 43
  • Tried Linux lsusb → identifies only VID/PID, no string description
  • Attempted generic drivers (CDC ACM, WinUSB, libusb) – no success yet

Hardware context:
This came from a cheap USB programmer/TTL adapter purchased online. No markings on the PCB.

Questions:

  1. Has anyone successfully installed a driver for this VID_214B/PID_7250?
  2. Could this be a counterfeit Prolific or FTDI chip?
  3. Any known working .inf files for Windows 10/11?

Thanks in advance for any clues!

The USB hardware identifier VID_214B&PID_7250 identifies a USB 2.0 Hub manufactured by Ameco Technologies (Shenzhen) Co., Ltd. . Specifically, this ID is often associated with the 4-port hub controller chip. Hardware Identification

USB devices use specific numerical codes to allow operating systems like Windows, Linux, and macOS to identify them and load the appropriate drivers. Vendor ID (VID): belongs to Ameco Technologies (Shenzhen) Co., Ltd. Product ID (PID): signifies a USB 2.0 Hub Revision (REV):

refers to the specific firmware version or hardware revision of that chip.

This identifier frequently appears in low-cost consumer electronics, such as 4-port USB splitters, KVM switches (like the AIMOS AM-UK404), and integrated laptop hubs. Driver Information For the vast majority of users, no manual driver installation is required

Known Assignment

  • VID 214B is registered to Huizhou Kaisheng Technology Co., Ltd. (also linked to USB2.0 Flash Disk / generic mass storage devices).
  • PID 7250 commonly identifies a USB mass storage controller (often found in low-cost USB flash drives, card readers, or simple external storage adapters).
  • Rev 0100 indicates the firmware/hardware version 1.00.

1. The Breakdown

  • VID (Vendor ID): 214B
  • PID (Product ID): 7250
  • REV (Revision): 0100

Step-by-Step Troubleshooting and Fixes

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

Driver and OS support guidance

  • If the device is USB Audio Class compliant, modern OSes will likely use built-in USB Audio drivers with no vendor driver needed. Check audio device list after connecting.
  • If vendor-specific interfaces exist, you may need:
    • Vendor-supplied drivers (Windows) or a signed driver package.
    • libusb or hidapi to send control transfers for non-standard commands.
  • On Linux, use dmesg after plugging in to see kernel messages and whether the device was claimed by snd-usb-audio or requires a driver.
