FTDI FT232RL not working

Mon Dec 03, 2012 6:49 am

Hi! I need to have three serial ports available to software on the Pi.
I was going to use two of the FT232RL to give me the other two serial ports with a VCP.
It seams to recognize the device. I am using Soft-float Debian “wheezy” (just downloaded yesterday) from what I have read on the form better supports the device. I have installed the D2xx drivers using these sources:

http://www.ftdichip.com/Support/Documen ... nux%20.pdf
http://www.ftdichip.com/Drivers/D2XX.htm

When using the examples or trying to access the ports directly it seams that they don't want to work. (or it hangs) I read the other two form posts about this problem but I couldn't figure out how they fixed the issue.
Thanks for any help!
