jakaskerl . The cm4 in itself does not have usb3 hub. Instead, it has usb2 only. So i couldn't reach high bandwidth, thus i was looking for a way to get the data from the OAK-FFC 4P using a pcie connection ( i'm making a custom board). So i wanted to know how to do that. For example taking a close look to the OAK-FFC 4P , there are two pcie port: which one should i use ? Is there a special firmware / software setup ?
