How can I enable USB host on the other ports? Should I use the ohci-omap module? I'm not clear with the relationship between musb and ohci-omap, are they separate controllers? I can't get the ohci-omap work on my board, and I was confused by the kernel configs in "USB support" section. Is it enough to get ohci-omap work by just enable USB_OHCI_HCD? I notice there is a ISP1301 transceiver on the main borad, so is the isp1301_omap driver needed? I found it depends on OMAP_OTG, which is not selected by ARCH_OMAP2430, does this mean isp1301_omap dirver is not necessary for ohci-omap? Does anyone get the ohci-omap work? Can you give some help? Thanks, Damwid
