Calibre on launch shows spinning jobs wheel. Top menu displays "Device" and "Card A" icons. Both list folders available for scanning.

I was hoping to be able to place my library on the expanded micro SSD storage -- the "Configure this device" dialogue stores, at least, the unique folder name on the micro SSD card (which is duplicated for the "Device" and "Card A").

A "driveinfo.calibre" file was written to the "Internal shared storage/Document" folder on Calibre launch.

Just wanted to add for anyone interested..

Mounting the Supernote Manta on my Linux computer as an mtp device and then connecting to the mount point/folders works beautifully -- just requires an extra step (versus automatic detection and book device status update).

Note: the device should be configured to NOT upload metadata from the device (mtp folder) as this can be quite slow if the library is large. Updating the metadata from Calibre to the device, however, is swift.

This is a more than adequate solution to the above reported error (when the Supernote is mounted as an mtp device, Calibre does not autodetect it, hence, does not produce the error).
