Vivien Thanks for the answers, but I am still having difficulty (see commands below). As you can see, the installer seems to believe that the latest version of libftdi (libftdi1) is already installed, but when I run libftdi-config --version it still indicates that the version is 0.18. What gives??
Thanks again John Battle $ sudo apt-get install libftdi1 [sudo] password for jobattle: Reading package lists... Done Building dependency tree Reading state information... Done libftdi1 is already the newest version. libftdi1 set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. $ libusb-config --version 0.1.12 $ libftdi-config --version 0.18 On Tue, Jun 5, 2012 at 12:42 AM, Vivien Giraud <[email protected]> wrote: > On 06/05/2012 02:00 AM, John Battle wrote: > >> Hi >> >> I have a couple of questions regarding libftdi/libusb on Linux 64 Bit >> (Kernel 3.0) Ubuntu 11.10. >> >> I am attempting to communicate with a FT2232H and would like some advice: >> >> 1.
