ColorSoft && Mac Error

InnovationHack · 04-19-2025, 03:19 PM

Trying to use my Kindle color soft with Calibre -- this is the error I get when I plug in the kindle (on Mac).

Failed to upload file named: metadata.calibre to ('Internal Storage',): 2:PTP Layer error 02ff: send_file_object_info():Could not send object property list.

2:Error 02ff: PTP I/O Error

Traceback (most recent call last):

File "calibre/gui2/device.py", line 111, in run

2:Error 02ff: PTP I/O Error

How do I fix this?

That is an error communicating with the device. Usually, this kind of error can be fixed by
following the steps below in sequence. First:

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

If none of those work, you can use one of the wireless communication methods described here:
