Does not reliably recognize Kindle Fire - Page 2

Try sending that particular file via nautilus to the sd card. Create a dummy file named driveinfo.calibre with some random text in it and use that. Remember to send it to the root of the SD card, which is where calibre tries to send it.

It may be that SD cards require some special setup to work with libmtp that calibre is not doing, but I cannot think of what that may be.

Yup. Did that first thing. Success via Nautilus. [For what it's worth, the same setup works fine with Calibre for my Sony prs-t1 with a 8gb microsd card; I tried the Fire with the 8gb sd card and same error so it's not tied to the card size].

The t1 does not use MTP. If you want to debug it more you'll have to get calibre built from source (as mtp involves a native code module), then insert debugging into this function: https://github.com/kovidgoyal/calibr.../libmtp.c#L464

See where it is failing (during the initial send or during getting the file metadata after the send). Although, I dont really see anything that could possibly go wrong in that function, compare it with the canonical send file example in the libmtp source code: https://github.com/mmalecki/libmtp/b...les/sendfile.c

Actually, looking through the libmtp source code, I found one possible cause of this issue: try this commit:

Had trouble with calibre build environment but got libmtp.so to build. The problem is in sendfile not file_metadata.
---
0. NAME driveinfo.calibre, parentid = 0 storageid = 65537 size = 290
1.After SendFile 0
2.file_metadata called and returned 7ff2cc15ee88

0. NAME driveinfo.calibre, parentid = 0 storageid = 131073 size = 288
1.After SendFile -1
Failed to upload file named: driveinfo.calibre to (u'Storage device',): 2:PTP Layer error 2002: send_file_object_info(): Could not send object info.
2:Error 2002: PTP: General Error
----

I downloaded the libmtp examples and tried using mtp-connect sendfile but got nowhere. Will try to look at this again this weekend.
