Connecting USBs

Today ,if I see, most electronic devices have a USB facility on them.I can connect my device to any computer system that can detect my device and connect the two systems for data transfer.But a negative that I observed is it is not possible to connect any two USB devices themselves and expect data to get transferred between them.
Now with the expounding of the USB,what I think has become necessary is that of a universal driver for USB devices that would enable any two USB devices to communicate and this is what exactly products from companies like 'Delkin Devices' for example do

'Delkin Devices'


Companies like these have come with 'USB bridges' which connect USB devices that store data in FAT16/FAT32 file system format.It will make the life of consumers easier in downloading song files from an USB storage device to an IPOD or storing pics from the camera onto a USB storage device and many more things..
