Kindle Oasis Connection Issue with New Version

cbeer86 · 10-05-2018, 06:07 PM

I have used Calibre for years with various Kindle devices, but since installing the latest update (version 3.32) today, I'm getting a very strange error with my Kindle Oasis (which I've been using with Calibre for a year or so).

I can connect the device to my computer just fine and manipulate files on it manually, but any time I try to send a book to the device memory from Calibre, my Kindle starts flickering back and forth between the home screen and USB connected screen as if it's being repeatedly plugged and unplugged from the computer. Eventually, either Calibre crashes or I get an error communicating with the device. I've restarted both my computer and Kindle several times and uninstalled/reinstalled Calibre twice. No idea what is causing this error. Any help would be greatly appreciated.

1) Try another USB cable.

1.5) Try another port on your Calibre computer

Had already tried both of those also, but thank you for the response. The connection to the computer is perfectly stable until I try to start the transfer from Calibre to device memory. I can even remove books from the device using Calibre, just can't send them to the device. Which is bizarre.

This sounds like a hardware issue on your kindle. There have been no changes to the kindle driver in calibre in a long time, but feel free to downgrade to an older release of calibre and check for yourself (old releases are linked to from the download page).

I'm not sure what would indicate a hardware issue when I'm able to edit files manually through file explorer (add/delete/move) with no problem, as well as remove/view files using Calibre. The only thing that causes this issue is trying to send to device using Calibre.

Finally got the error message instead of just a crash again. Will try installing an older version.

Version 3.22.0 produced a similar result, though it crashed much more quickly than version 3.32.0. Version 2.85.1 (newest version before 3.x) does not seem to recognize my device.

kovidgoyal · 10-05-2018, 10:03 PM

Hardware issues are typically triggerred by specific load patterns, that you can do N operations and the N+1th fails doesn't mean anything. And that error you posted is an IOError, which means calibre asked the OS towrite a file to the device, and the OS reported that writing of the file failed.

cbeer86 · 10-05-2018, 10:06 PM

Reinstalling version 3.32.0 seemed to work for one file, then produced a different error when I tried a second.

Sorry, just saw your second response when I posted that. I'm speaking to Amazon support now.

kovidgoyal · 10-05-2018, 10:18 PM

Just reset your kindle and if that does not work, get amazon to send you a replacement.

cbeer86 · 10-05-2018, 10:35 PM

Yes, they are sending a replacement now. Thank you for your help.

cbeer86 · 10-07-2018, 03:39 PM

The replacement I received had the exact same issue. I will request another replacement, but it seems unlikely that two different devices had the exact same defect...

cbeer86 · 10-07-2018, 03:46 PM

The new one is now not even being recognized by Calibre after one instance of this same error.

cbeer86 · 10-07-2018, 04:19 PM

I was finally able to borrow a friend's computer to try. Everything works fine there with my original Kindle. All other USB devices work fine with my computer, so it's clearly an issue specifically with connecting my computer to any Kindle device, which is bizarrely specific. Thank you for your advice, I will seek solutions to this problem in a more appropriate place.
