I have a board with isp1704, I only have to talk to it when I wanna e.g. ask it to detect if we have a charger attached to usb port. > Looking closer at your config options, you have CONFIG_USB_MUSB_OTG > which means you need a gadget driver loaded before you can use MUSB. > But, you also have CONFIG_USB_ETH=y, which means your gadget driver > is also built-in. So you won't need to insmod the module. Then it should be working. Do you attach micro/mini-A connector to usb port ? What happens in that case ? how about echo 5 > /sys/modules/musb_hdrc/parameters/musb_debug Does it give you any messages when you attach cable ? Send us dmesg output with musb_debug set to 5. -- balbi -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
