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.

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"

------------------------------------------------------------------------------------
ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
ftdi_sio 1-1.3.1:1.0: device disconnected
real baudrate used: 9600usb 1-1.3.1: BOGUS urb flags, 1 --> 0

this test should take 10.42 seconds
write failed at 0: usb bulk write failed

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.
