Hi,

I wonder why you complain.
This circuit has several mistakes. Read the datasheet and use the recommended circuit and part values.

Klaus
 
If possible can yu please provide any circuit
 

Hi,

Again: Read datasheet. There are example circuits.

Klaus
 
This is example circuit in datasheet still not detecting please help

Hi,

i often used the FTDI example circuits. They all worked.

Therefore I assume it´s a problem with your wiring...
Therefore we need to see YOUR circuit. With all part values and part names.

Hi,

This is the actual circuit we are using. When i plug the usb 2.0 to the computer it is not recognized. It shows unknown device. please have a look on the attached schematic.

Hi,

annoying.

WHY don´t you keep on the datasheet schematic? And then complain that it doesn´t work...

* no power supply for the FT
* no capacitor at 3V3OUT
* wrong connection of R23, R24
* wrong values of C38, C39
* Why R27?
... maybe more...

My last attempt: Please keep on the datasheet informations!

Klaus
 
0.1uF or 47pF? I suggest you to remove line capacitors at all if you don't see the difference.
