Usb Device-vid-1f3a-pid-efe8- Windows 11 !free! -

This is a detailed report regarding the USB device with Vendor ID (VID) 1F3A and Product ID (PID) EFE8 as it relates to Windows 11.

If Still Not Working

  • Try a different USB cable (must support data, not charge-only)
  • Connect directly to motherboard USB 2.0 port (avoid hubs or USB 3.0)
  • Check for Windows 11 update: Settings → Windows Update
  • Disable USB selective suspend:
    Control Panel → Power Options → Change plan settings → Change advanced power settings → USB settings → USB selective suspend → Disabled

Summary

VID_1F3A PID_EFE8 identifies a USB device (Vendor ID 0x1F3A, Product ID 0xEFE8). This guide covers how to identify the device, check drivers, install or update drivers, troubleshoot connection issues, and obtain device-specific firmware or vendor drivers on Windows 11. usb device-vid-1f3a-pid-efe8- windows 11

Understanding VID and PID

  • VID (Vendor ID): This is a unique 4-digit code (in hexadecimal format) assigned to a company by the USB Implementers Forum (USB-IF). The VID is used to identify the vendor of a USB device. In this case, the VID is 1F3A.
  • PID (Product ID): This is another unique 4-digit code (in hexadecimal format) assigned by the vendor to a specific product. The PID EFE8 identifies a particular product made by the vendor with the VID 1F3A.

9) When to contact vendor or replace device

  • If device is not recognized on multiple PCs, with multiple cables/ports, or shows hardware failures in Device Manager (Code 43, Code 10), contact vendor support or seek replacement.

8 Comprehensive Fixes for VID_1F3A PID_EFE8 on Windows 11

Preliminary Checks: Is It a Hardware Problem?

Before blaming Windows, run these two quick checks: This is a detailed report regarding the USB

  1. Test on another computer: Plug the device into a Windows 10 or Linux machine. If it works there, the hardware is fine, and the issue is Windows 11 specific.
  2. Try a different USB port and cable: Use a USB 2.0 port instead of USB 3.0. Older FocalTech chips sometimes have handshake issues with USB 3.1/3.2 ports. Also, replace the cable—a damaged data line can corrupt the VID/PID transmission.

If both checks pass, proceed with the software fixes below. If Still Not Working

8. Conclusion

  • VID_1F3A / PID_EFE8 on Windows 11 is almost certainly a logic analyzer based on the Cypress FX2LP chip.
  • It will not work out-of-the-box – manual driver installation is required.
  • The safest, modern approach on Windows 11:
    • Use Zadig to install WinUSB driver.
    • Use PulseView (Sigrok) with fx2lafw firmware.
  • If you have original Saleae hardware, use their legacy software (v1.2.18) but be prepared for driver compatibility steps.

5) Allowing unsigned drivers (temporary, advanced)

  1. Settings → System → Recovery → Advanced startup → Restart now.
  2. Troubleshoot → Advanced options → Startup Settings → Restart.
  3. Press 7 or F7 to "Disable driver signature enforcement".
  4. Install driver. This disables enforcement only for current boot—reboot to re-enable.
