I have a new PC with Windows 11 so I installed the latest MakeMKV beta (v1.17.3).

However, fresh from install it cannot open most DVDs I try.
It did open one disc but failed to rip:

All the discs I have tried are ones I have already ripped with the same version of MakeMKV on my Windows 10 machine using the same USB BR/DVD drive.
BD-ROM Slimtype BD E DS4E1S EA17 004260040586

Why would the same drive, with the same discs and the same version of MakeMKV work perfectly on Windows 10 but not on a brand new Windows 11?

because your band new windows 11 pc does not put out enough power on the usb ports for an optical rive

a powered usb hub may help

Interesting!

The port is specified to charge external devices at 3.0A so one would assume it could supply sufficient power for a USB optical drive...


Edit: Quite right though, plugged in another port and Bingo! Looks like I have a faulty port on a new machine.

Thanks!
