Glo Error communicating with device

snowstone · 11-04-2013, 06:01 PM

I'm getting the following error when I try to send ebooks to my kobo glo, this has happen before, but I disconnect and reconnect and I manage to fix it. But today that doesn't seem to be the case.

I read it could be a problem with the database and that a possible solution would be to log off and log in of my kobo account in the kobo glo. But by doing that when I log on it will update the firmware, something I do not want, because it will make the statistics of my sideloaded kepubs disappear.

Is there another way to fix it?

That looks like a problem with the book. The extended driver can convert epubs to kepubs during send. The conversion can fail due to issues with the books. Depending on the problem, doing an epub-epub conversion might fix the book so that the extended driver can convert it. But, you should report this in the extended driver plugin thread or as a bug against so the author can look into it.

I have already reported the error. But I wasn't sure it was a problem with the plugin, calibre, or the kobo.
I have tried to convert epub to epub, and still get the error

I really didn't want to loose my reading positions, highlights and statistics

Anyway of baking up all of the above?

Going by what you posted and davidfor's response, your database is okay. The file you are trying to convert is the issue and it is never being sent to your Kobo. You might want to download epubcheck and it's GUI or Sigil (built-in Flightcrew epubchecker) to check the file out before you blow away your database.

It's also possible that you have a corrupted file which re-downloading might fix.

One quick question is if you simply drop the book on your Kobo as a .epub, does it work or does your Kobo hang while trying to process it?

Regards,
David

I agree with what the other David said. It sounds like a problem with the book rather than the device. Another test to do is send another book. I suggest getting an epub from the library here at MR and sending that. These are generally well constructed books. Plus, if there is any problem with it, we can download it and test.

I just looked at the line of code the error refers to. Can you open that book with the calibre viewer?

I can open the ebook on calibre without problems.
I have F/W version 2.8.1 (9a63806202, 7/15/13)
I have tried epub to epub, and still didn't work.

I'm going to try a ebook from the library here to rule out problems with the ebooks.

Have tried send a converted epub from mobi (https://www.mobileread.com/forums/sho...d.php?t=128447)

And even tried to upload calibre quick start guide, both were met with the following:

Also when I try to open kobo as an flash drive, I'm met with an empty screen, like I had nothing there. I can't see the files I have inside my kobo, or folders.

This is looking like there is an issue mounting the drive. What happens if you connect without calibre running? Can you access the drive? Copy files to it?

What OS? There have been reports of Macs mounting the drive readonly which causes problems.

I'm using Windows XP SP3. Haven't tried it yet.

There have been previous issues with Windows XP SP3 and AMD chipset motherboards not communicating with Kobo's ereaders. On my computer, updating the AMD USB filter driver seemed to help but locating the correct version for a specific chipset is not much fun.

One other odd possibility comes to mind -- at one time, I was using a 2GB uSD card and it had been formatted to FAT and I simply ran out of directory entries. Copying the files off the card, reformatting to FAT32 and copying the files back fixed that problem.

I'd suggest trying the other David's suggestion about connecting your Kobo without Calibre and reporting if you can you see the files on the drives or do they still show up as empty.

Regards,
David

I have no card on my kobo, only using the main memory.
What I still don't get is what happen for it to stop working, it only started to acted up in the last month maybe, so what changed?

Any tips on how I may get the drivers? Maybe and app that automatically detects and downloads the drivers?

Did you get a firmware update around the time it stopped working? You might want to connect your Kobo to the computer and then run error checking on the drive (just scanning the drive without the automatically fix errors option) to see if it comes up with any problems.

Otherwise, try the Kobo on a different computer to see if it mounts and reads on that computer.

That applet may help. Just before I upgraded the desktop to Windows 7, the last AMD video driver package installed an updated USB filter driver. Before that, I had spent time using Google to locate sites that had USB filter driver and the AMD chipset matching my motherboard.
