Why do you need to write a new driver?
Normally, all the USB storage devices conform to the USB Mass Storage
specification, which means that the usb-storage driver of the Linux
kernel can be used for them. There is no need for a separate driver for
each USB storage device, unless of course it doesn't comply with the
USB Mass Storage specification.
