Fix problems with KVM virtual media SCSI devices. When the rack1 has
connected a KVM console which supports virtual media devices, it may
happen randomly that the block devices are mixed up (firmware volume
becomes sdb instead of sda). This causes a lot of trouble in the
appliance software. So we needed to disable the virtual media devices.
Our simple approach to solve this problem is to move the initialization
of USB storage devices from the initial ramdisk phase of the boot to
the later OS initialization. So the internal disks are initialized
as regularly, getting their device names and then after that happened,
the USB storage is initialized.
