Windows Orca USB Setup
Hosts that have DeGirum Orca with a USB-C interface installed need a driver to enable its functionality. The driver is distributed as a Zip archive.
Download the driver: Orca Windows Driver
Unpack the ORCA driver .zip file. This can be done with Windows explorer.
Start Device Manager. Open the Power User menu by right-clicking on the Start button (or by pressing Win+X), then click “Device Manager”.
Find “AI Accelerator device” under “Other devices”.
Right-click on “AI Accelerator device”, then select "Update driver”.
Choose “Browse my computer for drivers”.
Click “Browse…”, then navigate to the folder that contains the driver files unpacked in Step 1. Check “Include subfolders”. Then, click “Next”.
