It could be the problem with libftdi 0.xx. Which version of libftdi are
you using? 0.20 is the latest one for the legacy libftdi-0.x release.

I remember that libftdi1-1.0 could help this last time
with one of the users. libftdi1-1.0 has been formally released recently,
but then the library name is changed so there may be minor changes
needed to build with libftdi1-1.0 instead of libftdi-0.xx.
