I started using Ubuntu(18.04) recently and to this moment I am very satisfied.
I am facing this problem with the Kindle Paperwhite not being recognized by the usb.
I have tested other devices and worked normally, only the Kindle is not recognized. it even turns on the charging light near the Power button.

I ran some commands in the terminal to try to identify if Ubuntu is recognizing the device and apparently this is not happening.

Among these commands one of them was ls /dev/ | grep sd

The output of the command was the same whether the device was connected or disconnected.

I tested it on other USB ports.

OUTPUTS with Kindle connected

$ sudo apt list *mtp* | grep installed

  • lsusb or lsblk when it is plugged in and not plugged in. I wouldn't expect it to show up as /dev/sd? – j-money Feb 28 '19 at 13:08
  • You can run lsusb to see devices coonnected to the USB bus. Also, just after connecting the Kindle, run dmesg and look for messgesg about new usb device. – Soren A Feb 28 '19 at 13:08
  • Yes, I've tried these commands and I've seen them in other posts here at AskUbuntu. but the output remains the same, does not change whether the Kindle is connected or not. I have already tried connecting it to other Windows computers and it worked. – PHFP Feb 28 '19 at 13:17

  • @PHFP please edit your original post rather than forcing us to read through your unformatted comment. Also as Soren said dmesg will be useful here as well, and rather than paraphrasing "... remains the same, does not change..." post the full output in your question – j-money Feb 28 '19 at 13:39
  • As a last-ditch try, sometimes for reasons not for mortal man to know, devices will connect on one USB port but not on another. – Carl Witthoft Feb 28 '19 at 13:58
  • Can you execute apt list *mtp* | grep installed and post the output of that command in your question? I use 'jmtpfs' to connect to my paperwhite. – Charles Green Feb 28 '19 at 14:11
  • @j-money Thanks for the advice, I just made the changes you suggested. The dmesg output is insanely big, have any problems in posting it? – PHFP Feb 28 '19 at 17:36
  • @CharlesGreen I just ran the suggested command and added the output in question. – PHFP Feb 28 '19 at 17:37
  • @CarlWitthoft I tried on other USB ports. – PHFP Feb 28 '19 at 17:38
  • Please execute 'sudo apt install jmtpfs' - you might need to reboot – Charles Green Feb 28 '19 at 17:52
  • @CharlesGreen jmtpfs installed successfully, system rebooted but kindle not recognized. – PHFP Feb 28 '19 at 17:58
  • dmesg | curl -F c=@- https://ptpb.pw then when it spits out a link, just post it in your question – j-money Feb 28 '19 at 19:29
  • @j-money done, output posted – PHFP Feb 28 '19 at 19:34

It was a problem with the JBL USB cable. From what I realized this cable only serves to recharge devices and not to transfer files.

From my experience, it can even be the connector which is flawed : tweaking it a bit inside the kindle slot mounted it.
