APX Driver Set Up
When installing Jetpack SDKs from a Windows host, a compatible USB driver is required on the APX device to detect the board.
Compatible Drivers
SDK Manager requires one of the following USB drivers to be installed on the APX (Recovery Mode) device:
- WinUSB (Microsoft) — Recommended. Microsoft's built-in generic USB driver.
- libusbK — Open-source KMDF-based USB driver.
- libusb-win32 — Legacy libusb driver for Windows.
If no driver is installed, or a different driver is bound to the APX device (e.g. VBoxUSB from VirtualBox), SDK Manager will not be able to detect the board. Please follow the steps below to install or replace the driver.
Installation / Replacement Steps
- Download required files:
zadig-2.9.exe
zadig.ini
- Place both zadig-2.9.exe and zadig.ini in the same folder.
- Set Device to Recovery Mode:
- Ensure your Jetson device is in Recovery Mode before proceeding.
- Run zadig and Install/Replace the Driver:
- Launch zadig-2.9.exe.
- Select the "APX" device from the device list.
- Make sure the target driver is set to WinUSB.
- If a different driver is currently installed (shown on the left), click "Replace Driver". Otherwise, click "Install Driver".
