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

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. How can I tell which library versions I have installed on a system?
2. Can I have more than one version installed at the same time?
I don't think you can.
3. I need to communicate in the high speed mode. Is there any advantage to installing libftdi-1.0 or can I just stick to ther version that got installed with the os installation.
If I remember well you need libftdi version 0.16 minimum for high speed
4. Is there a binary of 1.0 or do I have to build it from source (I had trouble getting it to build)
What is you problem ?
Did you try sudo apt-get install libftdi1 ?
5. How can I most easily test to see that I am communicating with the FTDI chip? Can I send a file and looking at the chip pins with a scope or something like that?
It's depend what do you want to do, if you want to upload an image to a target use OpenOCD, if you want to test your pins use a scope or a led connected on it.
6. What is the best way to get data into the chip at a rate of around 20MBPS? Serial or parallel or does it matter?
You can see source code of openOCD for this it could be usefull, maybe.
Thanks
