You do realize that many we use daily in other countries are Assembled in China.
What Language do you expect to use with it?
Calibre does not change the DEVICE capabilities. It only tries to makes use.
FWIW As long as the device (folders) can be seen by the Computer, Calibre usually can leave a Book file there (naming can be manipulated via templates)
Additional features are dependent upon what Calibre can access in the device VIEWER DATABASE (Calibre does not provide the device with a viewer)
