Resolution of key exchange failures - external USB?
Posted: Tue Mar 14, 2017 1:14 am
I'm running makemkv 1.10.4 on Slackware 14.1 with two different LG drives indicating support of AACS v61 (one internal SATA, the other external USB).
The internal drive appears to be working without issue.
However, the external USB drive (LG BP50NB40) is giving me the key exchange failures as shown below (and elsewhere in this forum) on any disk I try in it. Is this an issue inherent in USB drive operation or is there a new technology/feature that makemkv isn't yet able to work around? The disk being tested shows as using AACS v32, but even v16's do this as well.
Going off other (older) forum posts, I see some users fixing their own installation errors and such but a lot of cold threads that don't get resolved. Is this sort of issue any better understood at this point in time...?
Thanks,

Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive
Highest AACS version is v61 , MKB saved as /root/.MakeMKV/MKB_v61_TIME_STAND_STILL.tgz
The volume key is unknown for this disc - video can't be decrypted
