Hm, only some heuristics - very fragile, but maybe they work for you:
Output of mount: a mounted CD/DVD has usually a filetype of
iso9660 or udf and an ro attribute.
USB sticks, -drives, iPods, etc. are often mounted with the
flush attribute and might have filetype vfat
(not sure: ntfs, msdos).
pb> mount | perl -ne '@mnt = split /\s+/; print "Stick? $mnt[0] $mnt[2
+]\n" if $mnt[4] =~ /vfat|msdos|ntfs/ && $mnt[5] =~ /flush/;'
Stick? /dev/sdd1 /media/BLUESTICK
Stick? /dev/sde /media/IPOD
pb> mount | perl -ne '@mnt = split /\s+/; print "CD/DVD? $mnt[0] $mnt[
+2]\n" if $mnt[4] =~ /udf|iso\d+/ && $mnt[5] =~ /ro/;'
CD/DVD? /dev/sr0 /media/SOYLENT_GREEN
CD/DVD? /dev/sr1 /media/IX0712
.oO(mmmmmhhh Soylent Green™...)
lsusb -v lists the USB devices currently attached but not necessarily
mounted. Check e.g. for attribute bInterfaceClass 8 Mass Storage.
Though, you might find empty memory card readers, iPODs, everything that has
a filesystem interface...
pb> lsusb -v 2>/dev/null | \
perl -ne '$dev=$_ if /^Bus/; print $dev if /bInterfaceClass\s+8\D/
+'

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
