How to find USB Storage device PATH based on serial number?

If I find a serial number in /var/log/dmesg e.g SerialNumber: xxxxxxxxxxxxxx. How can I find the device and the path to this device? Do I need to enable the kernel module usb-storage? What will that do for me and how do I make it persistent? I've tried to use lsusb but the storage device doesn't seem to appear. I can however see it in dmesg without any errors. I need to find the USB storage device and make a file system on it.
