GACK the lack of /dev/sr0 is spurious.  At the point I looked
the (usb) drive was not plugged in.  When plugged in we have

brw-rw----+ 1 root cdrom 11, 0 Nov 11 14:55 /dev/sr0

Very sorry about that.

What is true is that when I insert a known good disk in the drive I do
*not* get a media subdirectory of /run.  With the old laptop with a
built-in drive with the same cdrom media I have /run/media/gottlieb
and a subdirectory of that directory has the contents of the drive.

All the following are on the new laptop with the drive installed via usb
and the known good media inserted

Returns nothing when the (usb) cdrom is out.  When plugged in the output
is

I put the entire dmesg output on my nyu website
http://cs.nyu.edu/~gottlieb/dmesg

thanks to all for your help and again sorry about looking for /dev/sr0
when the drive was not plugged in.
