![]() ![]() The Kobo utility shows the database as uncorrupted. It seemed like the root problem was with the USB mount, not the database. I did not try the sign out/in rather than the reset. I did restart the PC and device after the error happened. I didn't always check the error log in calibre, but when it occurred it was always with the same job after connection. However, I did try connecting the device to the laptop and didn't have any issues. I do have a laptop with Windows 10 but Calibre is not loaded on it. I was able to use windows to copy files (I side loaded custom fonts). I tried a USB 2 port just now and everything worked. I have been using a USB 3 port (same one I used for my old H2O). I tried different cables (including the one sent with my H2O2). Have you tried signing out of the Kobo account rather than a factory reset? This will rebuild the database on the device without needing to resend the books. Are you restarting the PC and device after the error happens? Is it always the same error? Or do you get that error and a different one later? I'm wondering if the last line has a different description or the line number in "driver.py" is different. Can you successfully use Windows to copy files to and from the device? Different USB port - If this is a USB 3 port, try a USB2 port. Different USB cables - a faulty cable can cause weird problems. It sounds like there is a problem with the connection to the device and when the calibre starts accessing the database, the connection fails. At the point where the error is happening, calibre is trying to read the database. But, if there is a USB error at the same time, it probably means something else is going on. That error usually means that the database on the device is corrupt. I have not upgraded to the latest firmware 3, due to the reported problem with statistics. ![]() I have tried upgrading the firmware to (side-loaded) with the same results. Kobo firmware version: (factory default). However, this action doesn't happen until after the error above.Ĭablibre version: 3.14 and using the latest Kobo utilities. There is also a corresponding USB error that causes the USB drive to disappear. The error I am getting is during the job "Get list of books on device".ĮRROR: Error: Error communicating with deviceįile "site-packages\calibre\gui2\device.py", line 87, in runįile "site-packages\calibre\gui2\device.py", line 510, in _booksįile "site-packages\calibre\devices\kobo\driver.py", line 1859, in booksįile "c:\t\t\apsw-9hooel\apsw-3.13.0-r1\src\cursor.c", line 236, in resetcursor I also worry that I may need to work with Kobo to return/replace it. Before I go back to zero, I thought I would see if there is another solution. I finally was able to get my entire library loaded on the H2O but the error started again today. This doesn't happen all of the time, but once it starts happening it seems to keep happening until I do a factory reset on my device. I am having problems with calibre generating an error when connecting to my H2O edition 2.
