IIRC, U-Boot's xHCI driver does not support Intel > controller yet. No, The USB port is not detecting any devices. In the board only the upper USB port detects the hardware like USB-mouse and USB-keyboard ., The lower port is not detecting any hardwares. Ya I am seeing that eXHCI driver being used, but atleast both ports should detect the USB 2.0devices.
In the minnowmx.h file the maximum controller count is defined to be 1. May I know what it corresponds to? #undef CONFIG_USB_MAX_CONTROLLER_COUNT #define CONFIG_USB_MAX_CONTROLLER_COUNT 1 Thanks & Regards, Vinothkumar _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
