I did this with 2.4 a few months back. Basically all I did was add the same delay before mounting root as the kernel does with mounting a root floppy. Problem is the kernel is too fast for the usb code to find the disk.
I'v been wanting to ask this question. How can I make the kernel "sleep" for say 5 seconds (or pause or something, whatever is required to delay execution) to wait for the device to become available. I tried the same thing doing nfsroot with a cardbus nic which fails because the kernel doesn't see the card until after it attempted to mount /
