I have tried as you up to adding break and debugging to booting parameters. Then I have tried ls /dev/sd* and same its not showing sdb. I have waited for sometime
But its still not happening.
So just my curiosity forced me to remove USB even system running on initramfs mode and I reinserted USB again and it shown up right away.
Then I type exit and its starting booting.
Than you Ian and I hope this will help others to solve their issue quickly.
