Maybe you can parse the output of these commands, and piece the information together: 
~$ lsusb
....
Bus 001 Device 005: ID 0424:2602 Standard Microsystems Corp. USB 2.0 H
+ub
Bus 001 Device 010: ID 13fe:3100 Kingston Technology Company Inc. 2 GB
+ USB stick
...


~$mount
...

+s,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush)


~$ ls -l /dev/disk/by-path/
