Remember USB 3.x is the 'Blue' USB plug not the black.Tools of this type can cause a variety of problems, and if you look around the web, you can see plenty of instances of people experiencing those problems. Remember to load the Kinect SDK 2.0 and also update the driver to the 2016 driver (SDK 2.0 comes with the 2014 driver). You might be able to use a USB 3.1 PCI card as long your MotherB will carry it. I too suspected the power supply at one point, nope, I thought I had a broken Kinect (bought a second, nope, now I own two.) I also have two laptops, a VAIO and a Lenovo, which were built after 2013 (when they changed to USB 3.1) and it runs fine on both of those machines. I have two five years old big rigs (Z68X-UD3H-B3, i7-3770K, and a 970a-D3, FX-8350) and it constantly disconnects.

USB 3.1 is also known as 'SuperSpeed' or 'SS10' which goes up to 10 Gbit/s. It's often mislabelled as USB 3.0 in marketing material. You need USB '3.1' and controllers usually manufactured after 2013 have it. I think it has to do with the USB 3.0 version, older machines won't run it. (Having onboard graphics or a second PCI-Ex16 slot will definitely come in handy here). If you confirm it is Gen2 (or PCI 2.0) try to use that slot to put a confirmed-as-working-with-the-Kinect-2-USB3.0-card in it. You can use GPU-Z to determine which PCIe-Version the slot has where you got your graphics card plugged in - let the mouse pointer hover over the bus interface field and wait for the tooltip and it will reveal the PCI-e version of your graphics card as well as the one of your mainboard. For a Kinect 2.0 you need USB 3.0 and for USB 3.0 to run at super speed, you need PCIe 2.0 (or Gen2). After switching to a PCI-E x16 slot, the constant disconnecting was over.ĭon't confuse PCIe version and USB version here.

After some hours research I discovered that the mainboard (MSI K9a2 Platinum) had Gen2 PCIe for the PCI-E x16 slots, but not for the PCI-E x1 I had plugged the USB card into. In my case I had connected the adaptor to an USB3.0 card (Transcent PDU3). Read this, if you use an USB3.0 expansion card in a PCIe slot.
