I didn't find helpful threads elswhere (maybe I searched in the wrong way), so I try it with a new thread:
I've installed the latest Calibre on my Ubuntu 11.04 with Gnome 2.32.1
Now, when I connect the new Sony PSR-T1, which has a few books stored on the card, I get this message:
calibre, version 0.8.64
FEHLER: Fehler: Fehler bei der Kommunikation mit dem Gerät
[Errno 2] Datei oder Verzeichnis nicht gefunden: '/media/READER/Sony_Reader/media/books/Chaucer, Geoffrey/Canterbury-Erzahlungen - Chaucer, Geoffrey.epub'
Traceback (most recent call last):
File "site-packages/calibre/gui2/device.py", line 83, in run
File "site-packages/calibre/gui2/device.py", line 405, in _books
File "site-packages/calibre/devices/prst1/driver.py", line 196, in books
File "genericpath.py", line 54, in getmtime
OSError: [Errno 2] Datei oder Verzeichnis nicht gefunden: '/media/READER/Sony_Reader/media/books/Chaucer, Geoffrey/Canterbury-Erzahlungen - Chaucer, Geoffrey.epub'
The first lines mean basically: "ERROR: error: error when communicating with the device. File or folder not found: '/media....'"
In fact, the looked for file isn't there, but on the card, which is mounted separately by Gnome in a different folder. Calibre doesn't find it, or doesn't look for it.
