You can find this information in syslogd message or using dmesg command. Also have a look at API klogctl() which reads kernel log message in that you can find file system mapping of usb device.But you need to parsing on the the data Take some information of newly detected sb device from /proc/usb/bus/devices,using this info search for device mapping in the buffer collected using klogctl. This is the one way.
