Q: 8. Is there a replacement cable or model number for the USB cable? Or is only purchasable with the Magewell unit?

Q: 9. The USB cable included with this device is very short. What type A to type C cables are compatible with this device. Up until now the only cable I can find that will allow the card to be recognized by my 2019 MacBook Pro is the cable that was included with the card. Even though other cards seem to match the required specifications the device does not power on and is not recognized by the computer.

A: I am sorry to say that Magewell advises to please use the included Magewell USB 3.0 cable, which is a custom accessory. Using any other similar cable might cause capture problems and even damage the capture device.
