I'm trying to use usb host in an OMAP3 LV SOM board.
The board has one USB host port and one USB OTG port.
I built x-loader, u-boot, and kernel from the following URL:
git://gitorious.org/android-omap3logic/x-loader.git
git://gitorious.org/android-omap3logic/u-boot.git
git://gitorious.org/android-omap3logic/kernel.git
CONFIG_DEBUG_LL/CONFIG_USB_DEBUG are enabled in kerenl
After boot, usb devices can not be found via the USB host port.
I had tried the following:
(1) connect an USB device to the USB host port
(2) connect an bus-powered USB HS hub to the USB host port
(3) connect an self-powered USB HS hub to the USB host port
All can't work.
After boot, dmesg will have the following messages:
