Comment 18 for bug 1241505

I spent a little time with google search yesterday, trying to find out more about this.

Here's a link that I found:

I'm not quite sure what mailing list that is. But it looks like a discussion of breaking some of the USB code out of the kernel, and moving to ohci_pci. This is not code for keyboards and other devices. Rather, it is code for the USB host adapter that the keyboard is plugged into.

If I am understanding that correctly, then it becomes clear that ohci_pci needs to be in the "initrd", at least for hardware where it might be applicable.
