Welcome,
Take note. Rev 1.x board
1.1 x PCI Express x16 slot, running at x16 (PCIEX16)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
2.1 x PCI Express x16 slot, running at x4 (PCIEX4)
* When the PCIEX1_2 or PCIEX1_3 slot is populated with an expansion card, the PCIEX4 slot will operate at up to x1 mode.
3.3 x PCI Express x1 slots
(All PCI Express slots conform to PCI Express 2.0 standard.)
4.2 x PCI slots
Top full size PCIe x16 slot operates at x16. The full size slot below operates at x4. If you populate any of the PCIex1~3, the lower x4 slot will operate at x1 due to resource limitations.
If you aren't getting connectivity, the USB chipset on the expansion card is probably not compatible with the Kinect v2. Another card might work. What happens if you use one of the 3.0 ports on the Etron controller?
