hello,

i got my new likebook mars today and it is not recognised by calibre. i updated calibre to 4.8, and have no devices in the "ignored devices" list.
when i plug in the likebook the file manager nautilus mounts the device and i can access everything. now i read that mtp can only handle one connection. but when i unmount the likebook or shutdown nautilus it still does not show up in calibre. but also when i unmount it and want to remount it in nautilus i get a mistake. so i suspect that something is wrong with mtp.
my question now - does anyone have a hint how to restart mtp or read mtp logs or tell nautilus not to claim the likebook first ?

thank you very much
