Aja Video Port Devices Driver Updater

Select Update Driver. If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions. Reinstall the device driver. In the search box on the taskbar, enter device manager, then select Device Manager. Right-click (or press and hold) the name of the device, and select Uninstall. To restore the OEM drivers, follow these steps: Move the Oemn.inf and Oemn.pnf files back to the%Systemroot% Inf folder. Use Device Manager to remove the VGA video adapter, and then restart the computer. Windows Plug and Play locates the OEM video adapter and reinstalls the OEM drivers automatically.

For Windows version 1803 and later versions, if your platform supports the new Kernel DMA Protection feature, we recommend that you leverage that feature to mitigate Thunderbolt DMA attacks. For earlier versions of Windowsor platforms that lack the new Kernel DMA Protection feature, if your organization allows for TPM-only protectors or supports computers in sleep mode, the following is one DMA mitigation option. Please refer to BitLocker Countermeasures to understand the spectrum of mitigations.

Also users may refer to Intel Thunderbolt 3 and Security on Microsoft Windows 10 Operating System documentation for alternative mitigations.

Click Search for suitable driver, and then click Next. Click to clear all of the search option check boxes, and then click Next. Click Disable the device, and then click Finish. After you finish steps 1 through 7, Windows uses the Vga.sys generic video driver. This is the same VGA driver that Windows uses in Safe mode.

I suggest you to download the latest USB 2.0 Video Capture Device driver from the manufacturer’s website and try installing it in compatibility mode. Refer to the below link to download the driver for USB 2.0 Video Capture Device.

Symptoms

A BitLocker-protected computer may be vulnerable to Direct Memory Access (DMA) attacks when the computer is turned on or is in the Standby power state. This includes when the desktop is locked.
BitLocker with TPM-only authentication allows for a computer to enter the power-on state without any pre-boot authentication. Therefore, an attacker may be able to perform DMA attacks.
In these configurations, an attacker may be able to search for BitLocker encryption keys in system memory by spoofing the SBP-2 hardware ID by using an attacking device that is plugged into a 1394 port. Alternatively, an active Thunderbolt port also provides access to system memory to perform an attack. Note that Thunderbolt 3 on the new USB Type-C connector includes new security features which can be configured to protect against this type of attack without disabling the port.
This article applies to any of the following systems:

Systems that are left turned on
Systems that are left in the Standby power state
Systems that use the TPM-only BitLocker protector

Cause

1394 physical DMA

Industry standard 1394 controllers (OHCI compliant) provide functionality that allows for access to system memory. This functionality is provided as a performance improvement. It enables large amounts of data to transfer directly between a 1394 device and system memory, bypassing CPU and software. By default, 1394 Physical DMA is disabled in all versions of Windows. The following options are available to enable 1394 Physical DMA:

An administrator enables 1394 Kernel Debugging.
Someone who has physical access to the computer connects a 1394 storage device that complies with the SBP-2 specification.

1394 DMA threats to BitLocker

BitLocker system integrity checks mitigate unauthorized Kernel Debugging status changes. However, an attacker could connect an attacking device to a 1394 port, and then spoof an SBP-2 hardware ID. When Windows detects an SBP-2 hardware ID, it loads the SBP-2 driver (sbp2port.sys), and then instructs the driver to allow for the SBP-2 device to perform DMA. This enables an attacker to gain access to system memory and search for BitLocker encryption keys.

Thunderbolt physical DMA

Thunderbolt is an external bus that allows for direct access to system memory via PCI. This functionality is provided as a performance improvement. It enables large amounts of data to transfer directly between a Thunderbolt device and system memory, thereby bypassing the CPU and software.

Thunderbolt threats to BitLocker

An attacker could connect a special purpose device to a Thunderbolt port and have full direct memory access through the PCI Express bus. This could enable an attacker to gain access to system memory and search for BitLocker encryption keys. Note that Thunderbolt 3 on the new USB Type-C connector includes new security features which can be configured to protect against this type of access.

Resolution

Some configurations of BitLocker can reduce the risk of this kind of attack. The TPM+PIN, TPM+USB, and TPM+PIN+USB protectors reduce the effect of DMA attacks when computers do not use sleep mode (suspend to RAM).

SBP-2 Mitigation

On the previously mentioned website, refer to the 'Prevent installation of drivers matching these device setup classes' section under 'Group Policy Settings for Device Installation'.
The following is the Plug and Play device setup class GUID for an SBP-2 drive:

On some platforms, completely disabling the 1394 device may provide extra security. On the previously mentioned website, refer to the 'Prevent installation of devices that match these device IDs' section under 'Group Policy Settings for Device Installation'.
The following is the Plug and Play compatible ID for a 1394 controller:

PCICC_0C0010

Thunderbolt Mitigation

Beginning with Windows 10 version 1803, newer Intel-based systems include built-in kernel DMA protection for Thunderbolt 3. No configuration is required for this protection.

To block a Thunderbolt controller on a device running an earlier version of Windows, or for platforms that lack kernel DMA protection for Thunderbolt 3, refer to the 'Prevent installation of devices that match these device IDs' section under 'Group Policy Settings for Device Installation' on the previously mentioned website.

The following is the Plug and Play compatible ID for a Thunderbolt controller:

PCICC_0C0A

Notes

The drawback of this mitigation is that external storage devices can no longer connect by using the 1394 port, and all PCI Express devices that are connected to the Thunderbolt port will not work.
If your hardware deviates from current Windows Engineering Guidance, it may enable DMA on these ports after you start the computer and before Windows takes control of the hardware. This opens your system to compromise, and this condition is not mitigated by this workaround.
Blocking the SBP-2 driver and Thunderbolt controllers does not protect against attacks on external or internal PCI slots (including M.2, Cardbus & ExpressCard).

Capture devices enable a computer to accept HDMI or SDI input from sources such as camcorders and D-SLRs.

The HDMI port on most computers is output-only and will not accept video input. USB cables that come packaged with cameras are generally intended for file transfer and most cameras do not allow for live video monitoring via USB.

Capture devices can be external devices that deliver HDMI or SDI sources into the computer over Thunderbolt or USB, or internal cards installed into an available PCI slot on a desktop PC that allow HDMI or SDI sources to be connected to the computer directly.

Support for Capture Cards

If you need help with using the Capture card in Wirecast, we ask that you contact the manufacturer as the 1st point of support. It’s possible that you need certain drivers or recommended settings to make it work with Wirecast, and they can best assist you with this.

Elgato Support (Windows only)

You may also able to find other users who found success with specific capture cards on the Wirecast Support Forum. Note: Telestream Support is unable to officially support any of the following capture cards. We will make every effort to assist you, but you may be asked to use the above resources.

Devices listed below provide information on their supported driver and the interface required to connect to a computer running Wirecast.

A device driver is a computer program that operates or controls a particular type of device that is attached to a computer.
