    DC3217IYE usb hub controller


      Hi there!


      I have a DC3217IYE NUC. It has two rear, one front USB 2.0 and an internal USB header for additional two ports (like the datasheet says).

      The Windows 7 DeviceManager shows two USB HUB with two separate USB host controllers. The problem is, that it looks like, that all 5 ports are on the same host controller.

      I need to connect two USB devices to two distinct host controllers (not ports!), because the bandwidth of one host controller isn't sufficient for both devices.


      My questions:

      Are there really two separate host controllers? If yes, then how can I use them?


      Is there a NUC which has two or more separet USB host controllers (HUBs)?


      Thank you!
