yes, kind of strange, no usb 2.0 on it. you don't have one of wiihacks recommended setups i would say. check the wanin hermes cios thread linked below, there you can get fresh/good .wad files to install.
check the recommended setup there/or just get 249rev20 if you really want to have the lastest in 249 to use it with neogamma. i like usbloading with cfg usbloader.
why not rip the left over discs to the usb hdd as well?
