Mass storage devices such as card readers show up as as USB devices. However the media not be inserted. In those situations the previous code would just fake a disk and call usbcreate_disk. This is inappropriate because it forms a 1:1 mapping of USB device to disk leading to the inability to remove the disk and/or handle "hot plug" card insertion and removals. To alleviate this issue introduce the notion of ready to the usbmsc structure. It tracks detached, not ready, and ready states. The polling routine is then used to track not ready to ready transitions thereby creating and removing disks appropriately. This handles the case of inserting and removing a card that shows up as a new disk. Booted recovery mode. Able to observe inerstion and removal of sdcard. Also able to insert valid USB flash drive to boot as well.
