I have a older Wii (LU50) and newer Wii(LU63). It seems the newer Wii has higher compatibility with my western digital USB hard drive. Sometimes, the newer Wii just can find USB device. I need to power cycle the Wii and USB drive several times to make it work. Is there any reason behind this? Did Nintendo change the USB hardware? I am using usbloader gx and cios13b.
