Also I suggest you capture the ethernet interface traffic first, then enable musg debug switch and post musb debug message out if the ethernet traffic is OK but 'ping' is still not OK since your issue may be related network instead of musb driver. thanks, -- Lei Ming -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
