The ramdisk may void the rootwait option, thus it won't solve the
issue.
Several approaches can be used to solve the issue.
1. extract the ramdisk on your usb disk to a separate empty parition
and specify the root in the cmdline, be sure to add the rootwait (or
rootdelay) option.
2. I remembered that that some one has posted the usleep support in
init program on the code review site, but i don't know where it is now
and it seems the code is in current updated source yet. Here is one
similar patch, and with that, you can add one line in your init.rc:
on early-init
sleep 7
