OnePlus 3T Connection Issues

All,

My device was connecting fine but this stopped working now and I got this error instead:

Failed to get children from device: hr=2147753993 facility=4 error_code=8201 description: No description available.

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 90, in run
File "site-packages\calibre\gui2\device.py", line 513, in _books
File "site-packages\calibre\devices\mtp\driver.py", line 217, in books

WPDError: Failed to get children from device: hr=2147753993 facility=4 error_code=8201 description: No description available.

I have already read several threads in this forum and I could fix the issue before with the very valid advice from kovidgoyal and others - many thanks for that. But now I don't get it to work again even when I tried all the instructions:

1) Try rebooting both the device and your computer
2) If that does not work, find the files driveinfo.calibre and metadata.calibre on the device
and delete them (you can use Windows Explorer or a file manager on the device itself to do this)
3) Reset the device

When I look at the jobs queue I find that the app is showing on the status column the files/directories it finds and at some stage about 20 - 30 seconds into the scan it stops with the error. When I repeated it does not stop at the same file (I thought there is a corrupted on the phone).

As I am running out of ideas, did anyone experience the same issue and could fix it?

Thanks for any help.

Windows 7 Version Question

The Calibre download page at:
https://calibre-ebook.com/download_windows64

has this statement: ''If you are using Windows 7 or Vista please, use calibre 3.48, which works with all Windows 7/Vista machines, from here. Simply un-install calibre and install 3.48, doing so will not affect your books/settings.''

I am currently using version 4.10.1 [64bit] with Windows 7 Pro 64-bit and having absolutely no problems. But, since I noticed the above statement (it took me a while to see it), I stopped updating Calibre.

BUT, since I have seen no problems, can anyone give me a reason why I should uninstall my current version and install 3.48? Also, since 4.10.1 works with my system, does anyone know why the most recent version (4.15.0) would not also work?

Many thanks for any :help:

Log my series from Calibre to my KOBO aura H2O

Hy!

So here's my problem:
Sometimes I have trouble making my Kobo download the content of my "series" column on Calibre as series on the device, and treat it as such. I have solved the problem several times by deleting all my books from the device and downloading them again but by doing it I'm deleting my reading progress from the kobo, it's pretty annoying to have to "mark as read" half of my books again and again...
I think I could prevent it by understanding what's going wrong, anyone can help me?

I don't know if it is the place where I should post it, but I have another annoying problem with my series:
Let's say I have the series "A Pink Cat".
Usually, when I sort alphabetically my series, I'm gonna have something like:

"A Blue Cat [1]"
"Green Cat [1]"
"Green Cat [2]"
"A Pink Cat [1]"
"A Pink Cat [2]"
"A Pink Cat [3]"
"A Red Cat [1]"

Well for some of my books, it's gonna be like:

"A Pink Cat [2]"
"A Blue Cat [1]"
"Green Cat [1]"
"Green Cat [2]"
"A Pink Cat [1]"
"A Pink Cat [3]"
"A Red Cat [1]"


It doesn't sort every book the same way, how can I solve it?

Hi all

I'd like to recreate the MS-Edge layout on the Calibre Ebook Viewer.

Here is an example. I love the spacing on left, right, & in the middle.

I can continue reading on Ms-Edge but it's not supposed to be a reader and lacks many features.

Can someone please help me with the custom CSS?

Thanks

Calibre doesn't detect Kobo

My wife has a Kobo Aura H2O she hasn't used in a while, and it has been a few years since I have transferred any books to it from Calibre. I am currently running Calibre 4.15 on macOS Catalina 10.15.3.

I have the KoboTouch (2.5.1) plugin enabled as well as KoboTouch Extended, and have tried using KoboUtilities to switch between the two drivers. Nothing I've tried has allowed Calibre to detect the connected device. I can't figure out what has changed, as this worked just fine the last time I attempted to connect the device to Calibre.

:help: Any advice would be greatly appreciated!

Thanks,
mdclanahan

EDIT: It might also be important to note that the Kobo is running firmware 4.20.14622 (8bb853a72a, 3/13/20). The device mounts in macOS but does not mount in Calibre.

email to kindle no longer sending series

A long time ago, I set up the metadata plugboard to add the series to mobi files emailed to my kindle. As of Jan. 13, 2020, this is no long happening. On Jan. 11, I emailed a mobi file to kindle and the series is there. But that's the last one it worked for. I've tried updating calibre, reentering the plugboard formula and I've looked through all the calibre preferences. I can't figure out what's going wrong.

Here is my metadata plugboard formula:
format -- mobi
device -- KINDLE2
source template -- {title}{series:| (|}{series_index:0>5.2f| #|)}
destination field -- title
the file name should to look like this -- Book Title (Series Name #01.00)
The files go through but only the Book Title appears on my Kindle Voyage and on my Amazon content docs page. I'm using a GMX email address, in case that makes any difference.

Any ideas or suggestions?

Kobo/Calibre password in the clear issue

May 12, 2020, 10:17 pm

I realize that the Kobo beta web browser is a barebones thing and doesn't do popup windows, but as many people have discovered here who password protect their Calibre library, because of this, the Kobo browser never prompts for the username and password.

The best solution offered so far is to either disable authorization or use this URL:

http://username:password@myserver.com:8881/mobile

However, that puts my username and password in the clear for any wifi sniffer or network analyzer, never mind anybody picking up my Kobo and seeing the info in the URL field. Even if I'm mistaken about the security issues, is there a way to configure the Calibre server to offer a login page instead of a login popup window? If not, how do I go about requesting such a feature? Thanks.

Hi all!

I have a Kindle Oasis 2 and have recently bought an Oasis 3 to take the overflow of my 9GB eBook collection.

I've renamed the devices as far as Windows is concerned but Calibre sees both devices simply as "Amazon Kindle"

Is there any way Calibre can be made to differentiate between the two?

Thanks in advance.

Kindle book cover thumbnails disappearing

May 16, 2020, 5:24 am

Uploaded my kfx files (converted epubs) with Calibre send-to-device to my new Oasis (2019). The cover art thumbnails on the home screen briefly appeared correctly but almost instantly vanished and replaced by the default blank cover. The kfx files had previously been uploaded to my old Paperwhite (2018) with working cover art thumbnails; but I tested again today and it's now showing the same behaviour as the Oasis. The last time I successfully added a book to the Paperwhite must have been within the last two months, has there been a kindle software update since then?
Looking at the system/thumbnails directory, Calibre is creating a correct image, but after ejecting the kindle and re-plugging-in, the same thumbnail file has been replaced by the 'no image found' amazon thumbnail. If I understand correctly, normally the kindle asks amazon servers for artwork for a sideloaded book, so presumably it is now doing this regardless of the presence of art in the thumbnails folder?
[update] Just checked, when Airplane mode is on, the cover art remains; as soon as airplane mode is turned off, the cover art disappears.

I can work around by replacing the 'no image found' thumbnail with the cover art (using save cover to disk) on re-plugging-in, but I need to note which thumbnail goes with which book before I eject!

[Pocketbook][epub2][Metadata] Attributes order

May 16, 2020, 8:16 am
$

Hello! I haven't find anything searching, so I'm writing this post.

In short: sometimes Calibre adds the Series metadata to ePub2 files as

Code:
  <meta content="Series Title" name="calibre:series"/>
  <meta content="1.0" name="calibre:series_index"/>
instead of
Code:
  <meta name="calibre:series" content="Series Title"/>
  <meta name="calibre:series_index" content="1.0"/>

This makes the Series metadata of the affected books be unable to be read by Pocketbook devices.

As I haven't yet managed to find the trigger, and since apparently this is a very old issue Pocketbook never bothered to deal with, there is a way to force Calibre to write the Nema attribute first and the Content attribute next?

Thanks you for the attention.

Update Advice for Calibre AppImage?

I have very limited space on my laptop running linux mint, so I try to keep as much on portable storage as possible. Thus, I'm using an appimage of Calibre 3.18 on an SD card. (The calibre library it connects to is also on that SD card.)

Any suggestions for how best to update it to 4.16.0? I have no coding background, so I don't understand what would happen if I copied the binary install code shown on the downloads page when I have such a weird setup. Does it matter?
