When I plug a usb 3.0 flash drive or a usb3.0 hub to UP Board through a USB3.0 OTG adapter, it is always recognized as a USB2 device (e.g. when typing lsusb -t, it's always sitting under "Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/14p, 480M" instead of "Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M". I have tried on both 4.4 and 4.2 upboard kernel. (Definitely using upboard kernel by verifying through uname -r).

When I plug these devices onto my PC instead, it looks fine sitting perfectly under "Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M".

Any suggestion? (or maybe my OTG cable is just rated for USB2 instead even it has the blue colored thing on the plug).

Extra:
I also had no luck with realsene through OTG adapter, but at least other USB storage device and hub still work. (Still waiting for my USB3.0 micro B Male to micro B male cable to arrive).

    Looks like there still are issues with the USB 3.0 port.

    Hi there,
    i have a Problem with the USB 3.0 Port (i have a 3.0 OTG Cable to provide me with a Type A connector).
    For testing, i plugged in an usb hard drive with 3.0 support.
    Because i use gentoo, my kernel is hand made. I have support for xHCI compiled in.
    When i connect the HDD everything works, but the device only goes up to 480M (high-speed, USB 2.0) and not 5000M (super-speed, USB 3.0). Have i something not compiled into the kernel which is needed? Usually this setup works fine, but i always tried only boards with real USB 3.0 and not OTG.

    Here is the output from dmesg:

    as you can see, the device really supports super-speed

    (Device can operate at SuperSpeed (5Gbps))

    Any advice?
