Fixed! Download & Transfer via USB Kindle Not Working

Posted by on .

Download & Transfer via USB is a function provided by Amazon which allows you to use the USB cable to transfer Kindle content from a computer to your Kindle Fire and Kindle e-ink device. Additionally, it offers a workaround solution to removing Kindle DRM. Recently, some issues occurred when trying to download Kindle books for USB transfer in Amazon website. Many users reported the download & transfer via USB feature is not working. So here I write this post with the purpose of helping such people to fix the problem.

Part 2. Trouble Shotting - Download & Transfer via USB Not Working

Problem 1. Unable Download & Transfer via USB - The download never starts

Trying download and transfer via USB, I'm getting a message that says "Success: Downloaded your Kindle content to your computer via Your Media Library". I have no idea what this means. There is no "Your Media Library" on my computer. The download never starts.

download kindle to computer via media library

When you click "Download & Transfer via USB", a pop-up window should open. However, a lot of browsers have blocked the pop-up window by default such as Chrome, Safari, and Firefox. So the firs time you use Google Chrome, Firefox or Safari, a notice will show "Download your Kindle content to your computer via Your Media Library", but then you will get nothing. The download never starts no matter how many times you click the "Download".

Solution Allow pop-up windows in browser settings.

1 For Google Chrome users:

For Chrome users, the first time you click the button "Download & Transfer via USB", a notice "pop-ups blocked" will appear in the upper-right corner of the address bar. You can just check "Always allow pop-ups and redirects from https://www.amazon.com".

pop-up blocked in chrome

You can also go to the "Settings" >> "Privacy & Security" >> "Site Settings" >> "Pop-ups and redirects" >> select "Sites can send pop-ups and use redirects".

allow pop up in chrome

2 For Firefox users:

For Firefox users, the first time you click the button "Download & Transfer via USB", a pop-up symbol will appear in the address bar. You just need to click "Options" >> "Allow pop-ups for www.amazon.com". Then the download box would appear.

If the notice does not appear in the address bar, you can also go to the "Settings" >> "Privacy & Security" . And then uncheck "Block pop-up windows", or click "Exceptions" and add www.amazon.com into the allowing pop-up list.

allow pop-up in Firefox

3 For Safari users:

Click Safari in the upper-left corner >> "Preference" >> "Websites" >> "Pop-up Windows". Change the status of amazon.com to "Allow".

allow pop-up in Safari

Problem 2. No option for Download & Transfer via USB

I click the Download & transfer via USB action on amazon site. The options in the drop down menu are the Kindle apps and Kindle Cloud Reader, but neither of them are selectable. So I cannot finish the download. Must I possess Kindle or Fire hardware to enable the download option?

no option for download & transfer via usb

"Download & Transfer via USB" is only available for Kindle e-ink device or Kindle Fire tablet owners. Kindle apps (on phones, tablets, computers) are not compatible with that function. That's part of the Amazon security as they don't want you to make copies.

Solution If you have a Kindle e-ink device or Fire tablet but still receive such an error when downloading the content, it seems that you haven't registered your Kindle device yet. Please first make sure that you have registered your Kindle device with your Amazon account and try once again.

If you don't have a Kindle device, you cannot download books from Amazon site. Please use Kindle app for PC/Mac/Android/iOS to download your Kindle ebooks.

Notice: Meet some problems when registering your Kinlde device? Read the article for a solution: Solved: Can’t Register Kindle.

Problem 3. Download an FSDownloadContent file, not AZW3 eBook File

On downloading a book through Amazon website to my computer and then USB transfer to my Kindle, Amazon downloads an illegible file called "FSDownloadContent", rather than the usual .azw3 or .azw file. Is this a problem with the download?

FsDownloadContent

This problem is related to Amazon downloads using Safari browser. The Amazon download is not compatible with some certain combination of Mac OS and Safari versions.

Solution Try downloading the book using a different browser (i.e. Chrome). Another possible solution is to try simply adding the ".azw3" file extension after the file name. Sometimes that solves the problem.

OK. These are all things about Download & Transfer via USB. If you have any more questions concerning this issue, just leave a comment below. Don't forget to download Epubor Ultimate if you want to remove Kindle DRM through this method.

Spot on help with the download and transfer via USB problem. I called Amazon about this and was told that "most books' DRM doesn't allow you to download to USB", which is a crock, so their own employees aren't informed. I would have thought Amazon and/or Google would have spotted this issue in the advance copy of the browser release. I would have thought instead of simply blocking the download, it would be preferable to throw up one of those "are you sure you want to download insecure content" messages.

Thank you *so much* for your help on problem 1 – I'd encountered Problem 3 (Safari issues) before, so I tried chrome and was utterly baffled that it didn't work. You're a lifesaver. <3

There's no need to allow insecure downloads. You can download the file by opening `Developer Tools` (F12 on Chrome and derivatives) and go to the `Network` tab, then proceed as described in `Part 1` and finally look for the second `FSDownloadContent` on the list, right click it and select `Open in a new tab` and the download will start.

Lifesaver, thaaanks!  Showing pix of problem 3 with your Register Kindle solution helped me zero in on my issue for my sixth generation kindle, after days of Google searches, unproductive phone calls to Amazon support, and tearing my hair out. You were my last stop before having to buy a new kindle! What also helped: accidentally finding my kindle serial number by double clicking on Settings - that was unknown by Amazon support, but apparently exists for older kindles.  Eventually, a supervisor said my problem was an easy fix: kindle was registered to my inactive Amazon account and had to be transferred to my husband's Amazon account, if I was using his account for library book transfers b/c every kindle must be registered to that user. Tip: supervisor was able to do that, despite my not having wireless!  (originally the Best Buy kindle had been registered to my account by the store using their wireless). You saved me money and my sanity!

Thank you for the directions. I never understand why a software "upgrade" seems designed to make things that previously were simple and straightforward, more difficult. Now I cannot select five at once to transfer, and have to tediously go through the process with each one. Thanks Amazon for hiring idiots for programmers.

Help, need a solution.  After selecting download and transfer via USB, I get the following message:
"You do not have compatible devices for this content..."
My kindle fire device is registered.  I have contacted Amazon, but their rep was unable to help.

On Firefox it is necessary to over-ride pop-up blocks. In the address bar, click on the pop-up symbol then click on open blocked pop-ups. The download box should then appear. Click on save.
I hope this helps.

Transfer thru USB doesn't download in windows 7 to my download folder using Firefox like it did before. But it does using Firefox on my MAC. Why does it work on one computer and not the other. This is how I get my library books as I have wifi turned off so books stay on the kindle way past their due date. I have some that have been there for years. Thanks for your help.

I got a "success" message but I cannot find the file. A search for all azw and azw3 files on my computer did not find the file I "thought" had downloaded. I use Firefox and the usual message that a file had been downloaded never appeared. Help?

Unfortunately this is happening with Safari as well. Very frustrating. Any suggestions for Mac users with Safari?
reply
07/29/2021 10:31:10
If you have Safari, it's the same fix as Firefox. You have to go to Safari preferences and allow pop ups from Amazon. Then it works.

can you further explain allowing Amazon pop-ups for us aging rookies?

And thanks!

Thank you so much for the fix for downloading kindle via usb. We were going nuts trying to figure this out, and of course I would never have thought of allowing the pop-up. I was not present when my husband first tried it, so I don't know if the message was there or not, but now it is fixed and working.

Seems to be broken on all browsers on 08/02/2021. Tried Chrome, Firefox, and MS Edge. All behave the same when attempting to download content via usb, a popup windows opens, and displays the endless circle of death, never asks for my kindle device or proceeds beyond that infinite revolving arrow.

Good to know that I'm not the only one having this exact same problem. I was doing fine using Chrome, then all of the sudden is stopped working. The problem also occurs with Safari.

It has nothing to do with pop-up boxes because I can still get the box for adding to collections.

Guess I'll try again tomorrow.

yes me as well. on the phone with the amazon support guy right now who is asking me to attach the file and send it via my email account!! He doesnt seem to understand that I need to download it first to send it as an attachment!! This is insane!! Hope someone here can help me!

Not working for me either.  I've tried Chrome, Safari, and Firefox on two different devices.

08/3/2021 18:26:48
Tried it with Vivaldi and Edge. Also getting the spinning wheel of doom. Hopefully if it is happening to a whole lot of people Amazon might (maybe, hopefully, please?!) get around to trying to fix it.

Same here - same problem, both with Chrome and Microsoft Edge.  I've used download and transfer via USB for years, but suddenly, all I get is popups and an infinite wait while the circle spins.  

BUT WAIT!

Just a moment ago I tried it again, so I could describe the problem accurately, and the download worked!  Did Amazon just fix something?!  I'm going to quick download everything I can, in case it quits working again!
