[Pkg-libburnia-devel] Bug#789260: libburn4: Incompatibility with Plextor PX-608CU burner

[Thomas Schmitt]

Hi,

This bug report let's me learn things which i never wanted
to know. X-)

Can you point me to a comprehensive description of the problem ?
(The Ubuntu bug report is somewhat scattered.)


I am now reading
  https://www.kernel.org/doc/Documentation/usb/power-management.txt

On my system, all files
  /sys/bus/usb/devices/*/power/wakeup
are either missing or contain the word "disabled".
The ones of the BD drives are missing.

  /sys/bus/usb/devices/*/power/control
has "auto" for the A-B.C and missing file for A-B.C:1.0.

Does this look safe ?


Have a nice day :)

Thomas
