Whenever a CD or DVD is inserted into the drive and mounted, wodim fails to
recognise the device unless given root previledges. I have two optical drives
(a master CD writer and a slave DVD writer) and I have just inserted, mounted
and then ejected a CD into the CD writer. This is the result for the command
wodim -scanbus as a normal user
-------------------------------
badshah@linux-vulp:~> wodim -scanbus
scsibus4:
4,0,0 400) *
4,1,0 401) 'HP ' 'DVD Writer 1035r' 'NH21' Removable CD-ROM
4,2,0 402) *
4,3,0 403) *
4,4,0 404) *
4,5,0 405) *
4,6,0 406) *
--------------------------------
Clearly the CD writer is not detected.
As a super user the following is the output of the same command
--------------------------------
linux-vulp:/home/badshah # wodim -scanbus
scsibus4:
4,0,0 400) 'SONY ' 'CD-RW CRX320EE ' 'RYK4' Removable CD-ROM
4,1,0 401) 'HP ' 'DVD Writer 1035r' 'NH21' Removable CD-ROM
4,2,0 402) *
4,3,0 403) *
4,4,0 404) *
4,5,0 405) *
4,6,0 406) *
4,7,0 407) *
---------------------------------
Under such circumstances cd or dvd writing becomes impossible as a non-root
user. It takes a restart for wodim to recognise all drives correctly again. If
both devices are mounted and then ejected, subsequently wodim does not
recognise a single device as normal user rendering cd/dvd writing impossible.
