Follow-up Comment #5, bug #38659 (project avrdude):
For r1097, the file not exists before, it's created but empty for raw data
(size=0) or starts with some expected stuff for hex-files (but the content is
missing).
For r1139, there must be something different. I guess - it can't be a hardware
or driver problem, if the previous software version can communicate without
problems and the new one stops with the same system, libraries and conditions
(just switch to other svn-version and call configure/make).
- A re-enumeration should not occur, because that will create a new node in
/dev/bus/usb/... with the wrong rights, i don't noticed.
- removing the ftdi_sio module not helps, same problem as before
Last time i started debugging, the application hangs inside
write_flush-function (especially the ftdi_write_data-call), previously used
ftdi_usb_purge_buffers, but without deeper knowlege - i don't know what's
going on.
Another problem is, if the previous application call failed (Ctrl+C) .. the
next call hangs at beginning with:

Looks like the initialization of the FTDI not works properly to start from a
clean starting line.
Maybe you can create a working windows binary with latest svn version, if it
is working with your hardware (just read a empty flash back in file), it
should working with my hardware too.
