In the kernel documentation, kernel-parameters.txt, I found a few
options that might be useful to you.

        rootdelay=      [KNL] Delay (in seconds) to pause before
attempting to
                        mount the root filesystem

        rootwait        [KNL] Wait (indefinitely) for root device to
show up.
                        Useful for devices that are detected asynchronously
                        (e.g. USB and MMC devices).
