Usb Vid 1f3a&pid Efe8&rev 02 3 Driver ((new)) -
Allwinner FEL Mode
This hardware ID ( VID 1F3A & PID EFE8 ) identifies a device in . This is a low-level recovery state used by Allwinner-based devices (like Onda tablets, Orange Pi, or Android TV boxes) for flashing firmware or unbricking. 🛠️ How to Install the Driver
The revision number, REV_023 , offers a subtle but important nuance. Different Oculus hardware revisions have, at times, presented slightly different USB power negotiation or isochronous transfer requirements. Users on community forums have reported that while an older sensor (REV 01 or 02) might work on a USB 2.0 port with a passive extender, a REV 02 3 (likely a late-production Rift CV1 sensor) often requires a USB 3.0 port with a dedicated controller, or it will fail to enumerate properly. If the driver fails to load, the solution is rarely a new driver file. Instead, it involves troubleshooting the USB host controller: disabling USB selective suspend, updating motherboard chipset drivers (especially for ASMedia or AMD USB 3.0 controllers), or using a powered PCIe USB expansion card. usb vid 1f3a&pid efe8&rev 02 3 driver
- Windows: Use PhoenixSuit (for flashing firmware images) or LiveSuit.
- Linux/macOS: Use the open-source sunxi-tools. You can check if the device is detected by running:
(This should return the chip version, e.g., "AW16" for an A13)../sunxi-fel ver
