Under Windows, you can probably use WMI for this, depending on
exactly what it is you're trying to do. If I read you right, you want
to
scan all devices, determine the removable ones, and then read stuff
off them.

If that's right, then something like this might do the trick on Windows
(untestedish - picks up my floppy and USB stick):

<code>
import wmi
c = wmi.WMI ()
removable_disks = c.Win32_LogicalDisk (DriveType=2)
# if you want CDROM as well, repeat with DriveType=5
</code>

This will give you a list of WMI objects, each corresponding
to a removable disk. You can access the drive letter via the
objects' .Name attributes, and do an os.walk or whatever on
them.

<code>
import os
for disk in removable_disks:
  for dirpath, dirnames, filenames in os.walk (disk.Name + "\\"):
    print dirpath # and do whatever else you want
</code>
