It should work if you have multiple seperate usb 3 hubs. If they show up under the same hub it won't work. On my Mac book pro when I plug them in they are listed seperately. So both can use the full super speed bandwidth.
One other weird quirk is on OS X I have to unplug the power to them and replug it in after they are plugged in to my laptop to get them to be listed as superspeed correctly.
I hope that helps!
Here is my result of lsusb:

Does the result show that my notebook has only one usb 3 hub? If it is a hardware problem, maybe I have to use workstation instead. Thank you so much for your quick reply!
How does ofxKinectV2 work with multiple Kinect V2? And what's the minimum hardware requirement for running them stably? As I use libfreenect2 on Ubuntu 14.04 with my notebook, when I try to run Protonect with 2 Kinects, only one of them will work, the other programs will break down with errors like this: [Error] [protocol::UsbControl] failed to set configuration! LIBUSB_ERROR_OTHER Other error. Try debugging with environment variable: export LIBUSB_DEBUG=3 . [Info] [Freenect2DeviceImpl] closing... [Error] [protocol::CommandTransaction] bulk transfer failed: LIBUSB_ERROR_IO Input/Output Error [Error] [protocol::CommandTransaction] bulk transfer failed: LIBUSB_ERROR_IO Input/Output Error [Info] [Freenect2DeviceImpl] deallocating usb transfer pools... [Info] [Freenect2DeviceImpl] closing usb device... [Info] [Freenect2DeviceImpl] closed [Error] [Freenect2Impl] failed to open Kinect v2: @2:6
Thank you in advance! The work is really helpful as it supports multiple Kinects!
