While most IOS versions have a USB module, it is limited to USB1, and its I/O throughput make some applications next to unusable when using USB mass storage devices, others have annoyingly long loading times.
The Wii game “Your Shape” changed this – it introduced IOS58, the first with an official USB2 module. Starting with the System Menu 4.3 update, IOS58 is available to every Wii.
Thanks to some serious work by tueidj, all homebrew applications can now utilize this USB2 module through libogc. The Homebrew Channel v1.0.8 is the first version supporting it.
IOS58 will be automatically installed when you update your Wii to System Menu 4.3. If you do not want to update, you can use Tantric’s IOS58 Installer.
Presumably to avoid modifying the kernel to load another module, IOS58 had its MSC module removed, which was unused. This module was added back in IOS59, since it is actively used by IOS59 for WFS.
