LG BU40N not recognized

Post by Eltonmaster »

Hi!
I recently bought an unflashed BU40N with the intent of saving some media.
I also bought an USB-Adapter to connect the drive to my PC. Everything seems to work so far. I can playback files from blu-ray but MakeMKV does not recognize the drive.
The listed information is the following:

OS device name: D:
Manufacturer: 000000
Product: 9999999999999999
Revision: 1.05
Serial number: MOBP8TE3008
Firmware date: 2124-04-23 13:47
Bus encryption flags: 17

Does somebody know this issue already?
Is the usage via USB-Adapter not supported?

Thanks a lot for your help (and great software ofc),

Most USB adapters only work flawlessy with SATA HDDs and SSDs, not with optical drives. I recommend the BENFEI. Works with Makemkv and allows firmware flashing.
