ERROR: Error: Error communicating with device

[JWood]

Hello,
I recently started using Calibre. I am using ver 0.6.37.
When I SEND TO DEVICE I get the error below.

ERROR: Error: Error communicating with device

The strange thing is, it adds some of the books (or News), even though it reported the communication error.

A second problem I having; after using the Calibre eject button, waiting until it disappears (the Sony icon) and then disconnecting the device, the screen appeared to lock up and on the bottom of the scree it reads:

1fskin:/l/string...

Your assistance is appreciated.

can you copy files to your device using windows explorer?

[JWood]

Yes. That works. I didn't even think to try it that way. Thank you. Do you have a link to a "best practice" way of putting files on the prs-600?
Is it better to use the Sony software for music, pics, etc. Calibre for ebooks that need to be converted. And windows explorer for everything that doesn't work with Calibre?
Also, is there a method to the folders that can help me better organize books, news, school work, etc?
Thank you again for your program and assistance.

Hi

I'm getting a similar error as well - PRS-505. Here is my exact message:

Error communicating with device

The reader has no storage card in this slot.

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 56, in run
File "site-packages\calibre\gui2\device.py", line 233, in _upload_books

File "site-packages\calibre\devices\usbms\device.py", line 734, in _sanity_check
ValueError: The reader has no storage card in this slot.

Using Calibre 0.6.37. According to Calibre I have 177mb free. I can successfully move files onto my reader with Windows Explorer and using Reader Library.

I'm not getting an error after ejecting the reader.

Thanks!

Ok - after working on this for an hour, I decide to post here. Then two minutes later I figure out my problem - it was still trying to send files to an SD card, and not the main memory.

Don't I feel silly.

Thanks for the great program!

It bears repeating often - do not run Calibre and the Sony library at the same time. They will both cache information and attempt to write out two versions of the truth. Both will lose...

Thanks for posting your solution. I never had this error until recently, so I don't feel silly. I just chose Send to main memory in a specific format & clicked .azw for my Kindle. The 2 books I wanted to transfer went to my Kindle.

I'm having the same issue, running on a Mac (PRS-500). I get the following two errors:

Is your 500 upgraded to the new epub firmware?

If this is the old (non-epub) firmware for the 500 then Kovid says to stick with 0.6.29 which you can find here. Version 0.6.29 is the last version of Calibre that supports connecting to the PRS-500.
