Hi edabaorders,
I build a USB to 485 converter using the FT232 chip unfortunatly it doesnt work. When I plug the device, the PC doesn't detect it. I think that it is a matter of driver.
Where can I find the USB driver for the FT232 chip ?

As you plug the usb cable the pc will ask for a driver (if driver is not installed already). If it is not so, then there is a problem with the hardware itself. Tell us exactly what happens when you plug the cable.

try PIC18F4550 with a USB interface, then build inside it your firmware to take the data received from the USB bus and send it through the USART module using 485 protocol, to ease the process use "Microchip USB framework for PIC18F and PIC24F", its a ready made USB firmwares for PIC, one of them is a CDC firmware which can make you PIC appear like a virtual COM port, the firmware is open which you modify in it as you like just you will need MPLAB 8.2 or higher and C18 compiler (academic version is free).
this solution is little bit harder but i think more flexible for future.
