This page describes how to install and troubleshoot DeGirum Orca devices with a USB-C interface.
Ubuntu Orca USB Setup
Enable and Update DeGirum repository
Install prerequisites:
sudo apt install curl
Download DeGirum public key:
For Ubuntu 20.04:
wget -O - -q http://assets.degirum.com/apt-repo/DeGirum.gpg.key | sudo apt-key add -
For Ubuntu 22.04 and Ubuntu 24.04:
curl -fsSL http://assets.degirum.com/apt-repo/DeGirum.gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/degirum.gpg
Add the DeGirum software repository to your APT sources configuration file:
For Ubuntu 20.04:
echo deb [arch=amd64,arm64] https://assets.degirum.com/apt-repo ORCA main | sudo tee -a /etc/apt/sources.list
For Ubuntu 22.04:

Suites: ORCA
Components: main
Architectures: amd64 arm64
Signed-By: /usr/share/keyrings/degirum.gpg' | sudo tee /etc/apt/sources.list.d/degirum.sources
Update package information from configured sources:
sudo apt update
Download and install DeGirum USB package:
sudo -E apt install dg-linusb
Troubleshooting
If the AI server does not operate properly, reinstall it using the steps in theAI Server Configuration guide.
Verify that a dg_orca
group exists and that the current user belongs to it:
cat /etc/group | grep dg_orca && groups | grep dg_orca
If the group does exist but the user is not in it, add the user via:
sudo -E usermod -a -G dg_orca <username>
If you installed DeGirum AI Server then verify AI Server operation:
degirum sys-info --host <hostname or IP>
Check for the ORCA
section in the output. If it is missing, reinstall the server following the AI Server Configuration guide.
Windows Orca USB Setup
Hosts using DeGirum Orca with a USB-C interface need a driver to enable the device. The driver is distributed as a Zip archive.
Download the driver: Orca Windows Driver
Unpack the ORCA driver .zip file using Windows File 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".
