Paul,

Until Cygwin switches to mknod for devices, /dev will be a virtual
filesystem in Cygwin (as are /proc, /cygdrive, etc).  As such, it won't
show up in the listing of the parent directory (i.e., /).  What you need
to do is create an actual directory for /dev, and the empty file entries
for all of its contents to be able to 'ls' them.  You can use a script I
posted in <http://cygwin.com/ml/cygwin-xfree/2004-01/msg00353.html> for
this purpose (it'll also create some Linux-style symlinks).
