When you use Jumpdrive, it uses a special u-boot mode to expose the flash devices as mass storage. If you boot a normal OS, that feature is not something that comes as default behavior since the USB port is usually used in host mode, so you need to set that up yourself, filling in a device descriptor in sysfs and then exposing it to the outside world... roughly along the lines of https://linuxlink.timesys.com/docs/wiki/...le_Storage
