Thanks to Charlie, I added a 2-slot PCI Express USB 3.0 Card into the PC, and now instead of these devices from the Kinect:

Bus 001 Device 006: ID 045e:02c4 Microsoft Corp.
Bus 001 Device 003: ID 045e:02d9 Microsoft Corp.

I get these:

Bus 004 Device 003: ID 045e:02c4 Microsoft Corp.
Bus 004 Device 002: ID 045e:02d9 Microsoft Corp.
Bus 003 Device 002: ID 045e:02d9 Microsoft Corp.

. . . which is unfortunately still not what I’m looking for when compared to what freenect expects. Not surprisingly, I still couldn’t run the example programs with the Kinect through the new ports either. So the next step is to wait for the v1 Kinect to arrive. I would start writing the program now, but I hesitate to run into more problems if I’m not able to test the program at every step.
