           Summary: Disc burning not working with LG portable Blu-ray /
                    DVD writer Model WP40NB30
           Product: k3b
           Version: 20.08
          Platform: Mint (Ubuntu based)
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: Burning/Hardware

SUMMARY
When I try to burn a DVD or Blu-ray in K3b using a portable USB connected LG
WP40NB30 drive, the burn process does not start. K3b gets stuck in a loop
trying to "Unlock the drive". The drive just repeatedly makes a clicking sound
for ever. I cancel the burn and the error message "unable to unlock drive"
appears in K3b. The drive is recognized by K3b and correctly reports when blank
media is loaded. The drive does play back discs using other programs such as
VLC on this linux system and successfully burns discs on my Mac OS systems
using Toast software.


STEPS TO REPRODUCE
1. connect USB drive and create burn project in K3b.
2. load blank media
3. click "Burn"


OBSERVED RESULT
Burn does not start and must be canceled

EXPECTED RESULT


SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Linux Mint 20
(available in About System)
KDE Plasma Version: ?
KDE Frameworks Version: ?
Qt Version: ?

ADDITIONAL INFORMATION
K3b disc burning does work on this system with an internal(SATA interface)LG
DVD only drive. Just the USB blu-ray drive does not burn. The computer is a
desktop with an  AMD processor and ASUS motherboard. Same result with the dive
connected to either the USB 2 or USB 3 ports.

Thanks in advance for your advice.
