Him you need to add considerably more detail to your query and repost, there is not enough information here to answer.
From the little that is here I would say that drivers need to be installed on a windows machine for the OS to recognise any new device being connected to the machine by an y means.
Clearly a driver has not been installed.
If the device being connected is an USB device you shoulg not be surprised if an older pen drive is not recognised by a newer machine or a newer pen/flash drive recognised by an older machine
Anyway, please add rather more detail and submit the query again
