Kindle not recognized

Having spent over ten hours yesterday, and several today attempting to resolve this problem, I am, finally, out of frustration, seeking assistance from the calibre community.

I have read tens of pages in the forums addressing similar difficulties, but none of the suggestions worked to solve my problem. Nothing I have done has enabled me to get calibre to recognize the Kindle 2 plugged into any of the computer's USB slots. The computer does recognize the Kindle is plugged into it as Removable Disk G:, but, again, calibre does not "see" it.

If I left click on the G: drive I get a message, "Please insert a disk into Removable Disk (G”. If I right click on the G: drive the message is, "You need to format the disk in drive G: before you can use it. Do you want to format?"

The Kindle shows the USB charging screen.

The following is the debug log for the calibre:

calibre Debug log
calibre 0.7.49
Windows-7-6.1.7600
Windows
('Windows', '7', '6.1.7600')
Python 2.7.0
Windows: ('7', '6.1.7600', '', 'Multiprocessor Free')
Starting up...

Any suggestions will be appreciated.

I believe your Kindle was at some time disconnected from your computer without properly "ejecting" it first. Below is a quote from another thread describing my experience as to how I personally determined why the same thing was happening to me.


What to do about fixing your immediate problem? The best first thing I can suggest is to powercycle your computer (turn it all the way off, then on again) and also restart your Kindle [Menu button -> Settings -> Menu button -> Restart (not Reset to Factory Defaults- that's overkill)]


umm... that should fix it. At least it did for me. I don't see that you should need to, but you could then also try going to Device Manager (Start button/orb -> Run... -> type: devmgmt.msc ). Under "Disk Drives" there should be "Kindle Internal Storage USB Device" listed. Right click it, click "uninstall," Click OK on the confirm dialog. After the Kindle driver is removed from there, click "Action" in the menu bar at the top and then "Scan for hardware changes." It should rediscover the Kindle.

Again, I don't think you have to do that, as the first suggestion worked for me, but it is still an option you can try.

Here's what I discovered:

Since I am using Windows 7 x64, ejecting my Kindle from "My Computer" or the "Safely Remove Hardware" system tray icon has a different effect than ejecting it from Calibre.

- If I "eject" my Kindle from either "My Computer" or from the "Safely Remove Hardware" systray icon, it will remove my Kindle from appearing in Windows and my Kindle will then come out of USB Mode while still plugged in;

- If I "eject" my Kindle from Calibre first, my Kindle will no longer appear elsewhere in Windows either but the Kindle itself remains in USB Mode as long as it is still connected. It is this method which I believe causes the Kindle to sometimes not recognize properly when reconnecting to the computer.

With this in mind, I always eject my Kindle from Windows rather than from Calibre.

My laptop, however, is running XP 32-bit, and never causes any issues if I eject from either location. I believe I read somewhere that the issue of Calibre not kicking the Kindle out of USB Mode is a problem Calibre has when running on 64-bit OSes.


All I know is, ever since I started ejecting my Kindle from Windows rather than from Calibre on my desktop pc, I no longer have any issues at all.

Thanks, chyron8472, for your response. This is the first opportunity I have had to respond to you.

I tried your suggestion without any success. The computer I was attempting to have recognize the Kindle is my Wife's PC, which operates the Windows 7 OS; the Kindle be longs to her as well. After the four days of working on her PC and Mac (I could get the Mac, and calibre, to recognize my literati, but it would not recognize my the Kindle!) I decided to try and get my PC (OS Windows XP) recognizing the Kindle and literati, which it has done!!! However, calibre only recognizes the Kindle! Sooooooooo, the struggle continues!

Oh, by the way, if you are having any difficulty with reading a book on calibre you may wish to try the "Starko Guide."

Thanks again,

fogstratus

I just experienced this issue myself. The problem (for me) was that my PC was assigning the kindle to drive D:, which apparently windows 7 did not like. Here is the fix:

(With your kindle plugged in)
1) From the desktop, right click your computer icon and click "manage"
2) click "disk management" in the left pane
3) in the right pane, right click "kindle" click "change drive letter and paths..."
4) click the "change" button and make sure the "Assign the following drive letter" radio button is selected
5) choose a new drive letter in the dropdown box to the right (I chose Z
6) Click "OK" and verify that you can now access the drive correctly.

HTH

This part worked exceptionally well for me - Thanks

I just encountered the same not-recognized problem with a basic Kindle, IV I think. Plus, when I plugged in the Kindle to the comptuer in off position, after several seconds or more it turned on to the last page read. Never saw that before. The USB 3.0 port, the one I usually use, otherwise worked fine. After trying every other solution mentioned, from rebooting to restarting to using a port on the other side of the computer, it turned out that merely changing the USB port on the same hub got it recognized. Strange.
