Ubuntu :: Finding The Mount Point Of A Particular Usb Device

I'm developing a little script that automatically detects the insertion of a usb device and tries to open the directory of this device in nautilus. I am using Python

So far I was able to sample and compare the changes that occur in the output of 'lsusb' command and get information pertaining to the addition and removal of usb devices.

Now I want to know if we can use that information (or some other info present in the usb sybsyste --/sys/bus/usb folder) to determine exactly where this device has been mounted.

I know you might recommend using 'mount' as a quick way to do the same. I have already done that, but the limitation is that mount only gives u the mountpoint information. How does one (using a program/logic) determine which mount point corresponds to which device.

If I were to plug in two devices together, and both were automatically mounted, how will I be able to tell which mountpoint corresponded to which device? the output of lsusb provides no information whatsoever about where the device is mounted. So its kind of a deadlock

from lsusb ive been able to gather : Device name, serial and bus number and device number

Another thing i've noticed is the 'autoplay'. Whenever I insert a my music player into my computer, it gets mounted automatically and I'm presented with options about simply opening the file or playing it with rhythmbox... now if all that was being done was polling the output of mount, they would not be able to know that the device inserted was a music player (that info u can get from the /sys/bus/usb folder only using the device class and subclass info). So obviously the two are linked somewhere...
