  • Question

  • Hello, 

    im having problems running two kinects on my main machine, when i connect both, i get  "device cannot start" error under Device Manager, already tried all combinations of USB ports

    the strange thing is that it doesnt happen in my secondary PC

    any suggestions?

    thank you!

  • each Kinect needs to be connected to a separate USB host controller. Have you verified that your machine has multiple controllers without other devices on them?

  • yup, it has two EHCI controllers

    i've found out that using an extra USB 2.0 PCI card for the keyboard and mouse, i can connect the kinects to the main board and have both working. But, it is still very unstable; if i connect after restart, one of the kinects will be intermittent under Device Manager; if i connect and restart, it seems to stick, but only in a certain combination of USB ports

    i will be trying with a USB 3.0 PCI-E card to see if the extra bandwidth helps..

    thanks for your help!
