I'm using sg_turs in wrapper scripts when using optical media, to
ensure that the drive has loaded media OK and is ready to continue
with other tasks. This is useful!

However, since upgrading to trixie, calling sg_turs against my optical
drives fails to work correctly:

$ sg_turs /dev/sr0 ; echo $?
Test unit ready: bad pass-through setup
0

But adding the "-l" to use "the lower level sg_pt interface" makes
things work again.

sledge:~/debian$ sg_turs -l /dev/sr0 ; echo $?
device not ready
2

This seems like a bug...

control: tags -1 +upstream

The behaviour is confirmed with the upstream tarball, on different
hardware (a magnetic tape reader):

# sg_turs /dev/nst0
Test unit ready: bad pass-through setup

I have taken the liberty of reporting this upstream :

Best,
