	Commands being sent are incorrect.	Refer to VISCA section of this manual.
The camera is not working at all.	No response or image from camera.	Disconnect power, and wait a few minutes, then connect the power again. Retry.

Important Notes Regarding USB Connectivity

USB 3.0 ports are backwards compatible with USB 2.0 devices. USB 2.0 ports are not completely forward compatible with USB 3.0 devices (some USB 3.0 devices will connect to USB 2.0 with limited functionality).

External USB hubs should be avoided (i.e. give the camera its own USB port on the device) as they are not well suited to transmitting HD video reliably.

USB extension systems must be fully compatible with the version of USB that you are using and must utilize and external power supply, when required. Always connect the HuddleCam directly to the device in order to associate the UVC drivers before attempting to USB any extension system.

USB power saving settings in the device's operating system should be turned off completely for reliable USB camera connectivity.

HuddleCam Cameras – Video (General to all HuddleCamHD models)

All HuddleCamHD cameras utilize the UVC (USB Video Class) drivers that are built into Windows, Mac OS, and Linux to stream HD video to your device via your device's USB port (USB 2.0 or USB 3.0 depending upon HuddleCam model). When your device successfully recognizes the camera, your device will register the HuddleCam as an “image device”. You can see this in your Windows Device Manager program (type “device manager” into the Windows search tool) as shown in the screenshot, below:

HuddleCamHD

152 Robbins Rd, Downingtown, PA, 19335, USA - HuddleCamHD.com | 1 800 - 486-5276

In this example, you can see the HuddleCam model in use connected as a fully functional USB 3.0 device (HuddleCamHD) as well as a USB 2.0 device with limited functionality (USB 2.0 Camera).

If your device has not connected to or has not recognized the HuddleCam as an imaging device (in which case, you may see a new “unknown device”, “Westbridge” or “CYTFX3” labeled device show up in Device Manager’s “Universal Serial Bus Controllers” section rather than in the “Imaging Devices” section), the HuddleCam will not be available to programs that utilize a camera. In this case, try restarting the device and reconnecting the camera via USB – and to a different available USB port, if possible.

Similarly, you can see a connected device in System Information on a MAC. See screenshot below:

In this example, you can see the HuddleCam model in use connected as a fully functional USB 3.0 device "HuddleCamHD" as well as a "USB2.0 camera" with limited functionality (USB 2.0 camera).

HuddleCam Cameras – Audio (Specific to HuddleCamHD models with built-in audio)

In the case of the HuddleCamHD model HC3XA-xx, the unit also has a built-in microphone array. Because of this, it also shows up as a UAC (USB Audio Class) device on your PC.

In this example, you can find the camera's mic system under Sound Controllers in the Windows Device Manager, shown as "HuddleCamHD Mic". If the camera is connected properly, the mics will show up here and be available to any program that is able to utilize your connected audio devices.

152 Robbins Rd, Downingtown, PA, 19335, USA - HuddleCamHD.com | 1 800 - 486-5276

HuddleCam Cameras – Serial Control (Specific to HuddleCamHD models with virtual COM)

Since the HuddleCamHD model HC3XA-xx also includes a virtual serial connection, the camera will actually make 3 separate connects to your PC: UVC for video, UAC for audio, and virtual com port for serial communication, as can be seen here:

This view uses the Windows Device Manager's "View by Connection" mode rather than the default "View by Type" mode, which allows you to "sort" by physical connection to see your connected devices. However, all 3 USB connection types may be viewed in any of Device Manager's viewing modes (just not grouped together like this).

Changing the Advanced Port properties of the USB Serial Port (right click on “USB Serial Port (COMx)” connection as shown above) will allow you to set the virtual Com Port address of the camera to match the Com Port settings of your PTZ controlling software (like the free “Remote PTZ Control Software” available at http://huddlecamhd.com/resources/
