I have a Gigabyte Brix GB-BXi7-4500 which comes with a half size mini PCIe slot already occupied by WiFi + BT card. I want to use a Magewell XI100DE-SDI video capture card which requires a host interface of PCI Express x1. As per my knowledge, both the mini PCIe and PCI Express x1 run the same standard but only differ slot physical sizes. I purchased mini PCIe to PCI express adapters and tried to connected the card to the host system. I also powered the adapter using a power supply from another computer. The adapter comes with a USB 2.0 port. I tried plugging in mouse / KB using the adapter USB port and they work. But i am unable to get the the card working. The Gigabyte doesn't even detect the card when plugged into the PCIe x1 of the adapter. Can somebody help me out?
