You can use different methods to get this like using udevinfo command, from sysfs, from /var/log/messages.

Using udevinfo:

for DEV in /dev/sd*; do
udevinfo -q env -n $DEV 2>/dev/null | grep "ID_BUS=usb";
done

Using sysfs:

Change this according to your need.

find /sys/bus/usb/drivers/usb-storage/[1-9]-[0-1]:1.0/|grep -wo sd[a-z]|head -1

Using /var/log/messages:

Grep the usb device in /var/log/messages file, when usb device is connected.

I hope USB device can be detected easily now.
