AJA U-TAP HDMI or U-TAP SDI does not need a driver.
UVC (USB Video Class) and UAC (Universal Audio Control) are technologies used by U-TAP HDMI and U-TAP SDI (USB Audio Class). Most webcams communicate with the host operating system. This eliminates the need for third-party driver installations or configurations on the device. Simply plug it in and launch the application, as device support is provided at the operating system level.
