Wii-Linux has had support for USB since the beginning. gc-linux added support for it in MIKEp1, the first release. Support in versions between gc-linux and Techflash's 4.5 port used to have issues. USB hubs sometimes caused strange behavior, and sometimes the driver threw -EINVAL (error -22) when a device is inserted. USB support was greatly improved with mainline and should be more reliable than past versions.
