Hi there I'm having problem getting USB 3.0 controller working properly on the Intel Denverton x86 board. First I tried to use xhci driver, but there doesn't seem to be any xhci driver or generic driver for x86 I only found the following xhci-exynos5.c: { .compatible = "samsung,exynos5250-xhci" }, xhci-mvebu.c: { .compatible = "marvell,armada3700-xhci" }, xhci-rockchip.c: { .compatible = "rockchip,rk3399-xhci" },
Then I tried to use ehci driver, as there is generic driver for ehci-pci ehci-pci.c: { .compatible = "ehci-pci" },
I added the section into device tree file usb_0: usb@15,0 { reg = <0x0000a800 0 0 0 0>; compatible = "ehci-pci"; };
When I run "usb start", U-boot is able to find the controller, but doesn't detect the usb keyboard or Pendrive which are plugged to the USB ports.
=> usb info 1: Hub, USB Revision 2.0 - u-boot EHCI Host Controller - Class: Hub - PacketSize: 64 Configurations: 1 - Vendor: 0x0000 Product 0x0000 Version 1.0 Configuration: 1 - Interfaces: 1 Self Powered 0mA Interface: 0 - Alternate Setting 0, Endpoints: 1 - Class Hub - Endpoint 1 In Interrupt MaxPacket 8 Interval 255ms
I see the following in the log. It doesn't find child devices when scanning. scanning bus 0 for devices...

I wonder if this is caused by using ehci driver on xhci controller? And currently is there xhci controller Driver for x86 based board?
