I am new to this list. I ran into two weird problems recently on a MCF547x board with ISP1561 as the usb controller. It seems that ISP1561 does not give the mass storage device ACK when issusing the GET_MAX_LUN command. This problem occurs when connect some usb disks to the system. Another problem is that usb system hangs up very rarely after system reboot. Under this situation reset fails to bring the system back. Only a cold boot (i.e. power off then power on) will bring the usb system back. Any clues? -- 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
