I finally got around to downgrading to firmware 2.4.0 today (2.4.0a from the MobileRead list of downloads). I immediately got the "error communicating with device" message so deleted only the 2 Calibre files of driveinfo.calibre and metadata.calibre and tried again.

I've been deleting and adding books in small increments and in large increments from 1 to 160 books at a time, multiple times without disconnecting the reader, and I've had zero problems. Not once did I get the "error communicating with device" message.

After I had all my books back on the device and renamed correctly, I disconnected the reader and then connected it again several times, deleting and transferring more books each time. Still no errors, and all the books actually remain correctly listed as being in my library. Before when they were renamed to include the series number and name by Calibre on sending to device, the Device side of Calibre would show those renamed titles as not being in my library.

I'll give it a few more days of connecting to the PC and see if this doesn't hold, but I'm very hopeful it will though because this is the furthest I've gotten without any communicating errors. With 2.5.1, one transfer or one deletion of one book would bring up the error, making it impossible to do much of anything through Calibre. And then as I said, all the renamed titles would be shown as not in the main Library.

I haven't noticed any bugs that affect me yet in 2.4.0, and I edited the version file to hopefully avoid any updates again. But I'm really hopeful about this working at this point after swapping books in and out all afternoon and not seeing any communicating errors.

Btw, I'm still on version 0.9.44 of Calibre. I haven't tried 1.0+ yet. When I do update Calibre, I'll report back if 2.4.0 is still working correctly. Before this downgrade, I was using 2.5.1 and have tried 2.6.1 and 2.8.1 and still had the communicating error with each Kobo firmware version.

I'm ecstatic at this point though after so many months of being aggravated trying to send books to the reader

.

Edit: I noticed that the metadata.calibre file when I'd get all the connection errors was always 18+mb. Now that it's all working as it should, the same file with the same exact number of books is only 2mb, which is all it is on my Sony readers.
