Help needed in Libftdi

I haven't experienced this issue myself. I'll have to check which version I'm using. I did however find this that you may find useful.
The nice thing about open source code is you can drill right down to where the problem is.

Help needed in Libftdi

Error comes when we run the code on gumstix --- uname -a "Linux overo 2.6.32 armv7l GNU/Linux"
While everything runs as expected on Host system.

following is the trace that comes after running the default "baud_test" example of "Lib-ftdi0.17"

------------------------------------------------------------------------------------

You'd need to provide me with more details. I'm not familiar with that error.
Does this occur when opening the port? Post more code fragments and I'll try to help.
