The GDM72xx USB WiMAX dongle itself contains a Linux system which is responsible to deal with the traffic between WiMAX radio and USB interface. I think em_download_image() for this USB dongle will be used when the Linux system on it has been broken and the dongle itself could not extract kernel and ramdisk from the firmware image. > greg k-h -- Best regards, Macpaul Lin _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
