This specific hardware ID is commonly found in the following consumer products: usb vid214b amppid7250 amprev0100 new

USB Switches: Used in 4-in/4-out USB 2.0 peripheral switches, such as the AIMOS AM-UK404.

Standalone Hubs: Integrated into standard 4-port hubs like the GINZZU GR-315UB or Maxxter ACT-HUB2-4P.

Combo Devices: Frequently embedded within multi-function devices, such as USB-to-Ethernet adapters that include additional USB ports. Driver & Compatibility

Driver Type: This is a "Class 09" device, meaning it is a standard USB Hub. It does not require proprietary manufacturers' drivers and instead uses the Generic USB Hub driver (usbhub.sys) provided by Microsoft Windows. This report identifies the USB device with the

Operating Systems: Fully compatible with Windows (XP through 11), macOS, and Linux.

Known Issues: Users have reported intermittent recognition on low-power devices like the Raspberry Pi. If the device is not recognized, it is often due to insufficient power from the host port rather than a driver failure. Technical Verification

To verify this device on your local system, you can use the Windows Device Manager to check the Hardware IDs under the "Details" tab of the device properties. On Linux systems, the command lsusb will display the device as 214b:7250 Huasheng Electronics.

If you're having trouble with the device, could you let me know: What operating system you are using? Where to Find the Correct Driver Do not

Where to Find the Correct Driver

Do not use generic "driver updater" scams. Use these legitimate sources:

  1. OEM Website: Check the bottom of your physical device for a brand and model number. Search that, not the VID/PID.
  2. Microsoft Update Catalog: Go to catalog.update.microsoft.com and search VID_214B. If Microsoft has certified a driver, you will see it.
  3. Snappy Driver Installer (SDI) Origin: Only the Origin version. It contains a massive database of ROU (Really Old) drivers, including obscure Anyka ones. Search within SDI for 7250.
  4. Anyka SDK (For Developers): Anyka provides Linux drivers and firmware tools to OEMs, but these are not public. You may need to contact the reseller.

Example interpretations

  1. Typical kernel-style entry (human-readable rewrite):

    • “A USB device from vendor 0x214B with product ID 0x7250 (device label ‘amppid7250’), firmware revision 01.00, was newly detected.”

  2. If you needed to match a driver:

    • Driver probe can match on VID/PID: match vendor=0x214B and product=0x7250. If the driver also checks firmware revision, it may verify rev 01.00 (amprev0100) and only proceed if compatible.

  3. For a udev rule example (pseudo):

    • SUBSYSTEM=="usb", ATTRidVendor=="214b", ATTRidProduct=="7250", RUN+="/usr/local/bin/setup-amp --rev 01.00"
