Yet another "Error communicating with device" question

sylvandale · 04-22-2022, 08:08 AM

Yet another "Error communicating with device" question, sorry.

I have used Calibre for many years with various devices. However I have had a problem setting it up with a new Lenovo P11 Plus tablet. Basically, when an SD card is present I get the "Error communicating with device" message, and when the SD card is removed it works fine.

I have seen many threads on this, so I realise it's probably a dead end, but I just wanted to check to see if there is any solution I have missed. I have bought this tablet mostly for use as an ebook and pdf reader, so I'm keen to try every possibility

What I have tried is:

1. The old turn 'em off turn 'em back on again routine.
2. Looking for the files driveinfo.calibre and metadata.calibre on the tablet. Obviously these don't exist until first calibre communication has been established, so if I try it with the SD card installed first then they are not there. Only once I remove the SD card are they then created.
3. Factory resetting the tablet. As it's brand new, and Calibre is the first thing I want to get working, this is not a big deal.
4. Different SD cards. I have a new 256GB card and and older 64GB card, both SanDisk Ultra cards bought direct from Amazon, not third parties. Both cards work fine generally and are recognised on the tablet and in windows.
5. Reformatting the SD cards, both on PC and on the tablet.
6. The SD cards are formatted as "portable storage" which I understand is basically what SD cards have always been, generally. I have not tried formatting as "Internal Storage", that just seems to me to be a recipe for other problems down the line.
7. Enabling USB debugging in developer mode on the tablet - not something I have seen on this forum but I read it somewhere else and thought it worth a go.

Any suggestions most welcome, please.

I can of course post the error log if that helps at all.

Many thanks

Posting the actual error is always useful.

This is the error:

Ah yes I'm afraid you have tried everything I know of to workaround that error.

I feared as much. But many thanks for looking at it (& for Calibre of course!)

Just a postscript, in case its useful for anyone else reading this in future:

I formatted the SD card as "Internal Storage", which, as I understand it, is where the tablet sees/uses the card along with the internal ram as a single storage. That works ok. The downside is that you can't remove the card, and I don't know what happens if the card breaks. But its worth it for me to get Calibre working on this tablet.

wildhoney66 · 05-14-2022, 01:19 AM

i am getting the same thing

Spoiler:

and from Debugging it i got this

wildhoney66 · 05-14-2022, 01:22 AM

but mine isn't for setting up anything it's cause i was putting books on Sunday night and it was working now it's not letting me remove books or put anymore on it my apologies for putting this in the wrong section i've never had this problem so i dunno where else to put it and this looked about as close to my problem. i did uninstall it and install it again and nada

kovidgoyal · 05-14-2022, 01:47 AM

delete the file driveinfo.calibre from the device and you should be fine.

wildhoney66 · 05-14-2022, 01:49 AM

how do you do that?

Use your file explorer (assumes connected by USB), to see the files on the device.

wildhoney66 · 05-14-2022, 02:00 AM

yeah the cord isn't that long either it's connected to my PC

wildhoney66 · 05-14-2022, 02:12 AM

I have just tried adding my Lenovo P11 to Calibre and keep getting exactly the same error verbatim. Is the above workaround the only fix for this problem on Android tablets? If so, that means I can't use Calibre on my tablet, which is a shame. If there was some way to get Calibre to install to internal storage instead of the SD card, that would be great.

theducks · 07-06-2022, 10:16 PM

On?
Calibre does not run under Android AFAIK.
Most tablets are reading devices. Did you mean 'connect'?

My Android based Moto 7 requires me to specify how to use the USB connection EVERY TIME I attach the cord: File Transfer mode is my choice. (other modes have different limits/actions)
