I'm figuring this is a long shot, but has anyone had any luck with using an adapter that would take a USB 3.0 female connection on your laptop and convert it to a PCI Express Slot (or Thunderbolt) to take advantage of running multiple cameras though vMix? If so, what setup has successfully worked for you. I'd like to know before spending money on an express capture card only to find out it won't work.

Thanks in advance
