You need to provide COMPLETE details of your problem. I suggest
enabling tracing and sending the full log to the list.
The log is attached. I did further debugging and found that ssh via open
ssh succeeds, however when I enabled verbose option on it, I see some
lines that are interesting

This shows that the remote protocol version is 1.99. Does libssh2 work
with that ? I would assume no, but the folks using this device claim
that it used to work and then suddenly started failing without any
change to the device.
Thanks,
Jasmeet
it seems the problem went away after compiling with -D_REENTRANT. I
tried this but it didn't help. Unfortunately I can't access the
associated ticket as libssh2 trac is down.
Try now. http://trac.libssh2.org/ticket/99
