Xubuntu 14.04.5, all updates applied.
I have a program that can't find ether of my optical drives, /dev/sr0
and /dev/sr1. Apparently there is a new module, 'sg,' that calls
them /dev/sg0 and /dev/sg1, and those are all that the program will
look for. I can't tell if I have the module installed or not:
sudo modprobe sg - returns nothing, no error messages
lsmod | grep sg - also returns nothing
ls -la /dev/sg* returns:
crw-rw----+ 1 root cdrom 21, 0 Jan 23 16:33 /dev/sg0
crw-rw---- 1 root disk 21, 1 Jan 23 16:33 /dev/sg1
crw-rw----+ 1 root cdrom 21, 2 Jan 23 16:33 /dev/sg2
crw-rw---- 1 root disk 21, 3 Jan 23 16:33 /dev/sg3
crw-rw---- 1 root disk 21, 4 Jan 23 16:34 /dev/sg4
crw-rw---- 1 root disk 21, 5 Jan 26 23:00 /dev/sg5
ls -la /dev/sr* returns:
brw-rw----+ 1 root cdrom 11, 0 Jan 25 17:46 /dev/sr0
brw-rw----+ 1 root cdrom 11, 1 Jan 23 16:33 /dev/sr1
Synaptic lists no module 'sg,' although it does list 'sg3_utils and
'sscsitools-gui,' which I installed. I can't figure out how to use
either one, no man pages and no way to launch the GUI.
According to http://sg.danny.cz/sg/#mozTocId689512 the latest version
of sg is 3.0.19.
If it matters, uname -a gives:
Linux Devil-Bonobo 3.13.0-139-generic #188-Ubuntu SMP Tue Jan 9
14:43:09 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
I can't tell is the module is installed or not. Evidence is confusing:
1) the program still can't find the devices
2) lsmod doesn't find it
3) modprobe returns no error messages
4) ls -la /dev/sg* shows the devices
I could use some suggestions.
