Calibre doesnt see any device

[ioman3]

I have tried updating Calibre to latest version, running as admin etc.
I have Lenovo Yoga computer with Win 10.

My device si Android reader with SD card. I also tried connecting the SD card directly using card reader.

Here is the calibre debug output:

Yur device has to show up as a drive in windows explorer before calibre can connect to it. According to that debug output windows isnt seeing it.

As for connecting to a sd card directly, you can use the connect to folder function in calibre.
