Hi. I want to create USB --> UART converter. Here is my scheme . When i connect it to pc i see Unknown Device. I check it in program USB View and there is ConnectionStatus: DeviceFailedEnumeration and in all other places are zero. Is problem in my scheme or what? Thank
 

Hi,

Did you install the FT232BL driver file in your PC?

Since you have used the usb bus powered configuration, make sure that your circuit did not take too much current as mentioned in the datasheet.
 

Ferrite bead is missing in ur schematic which is used to nullify emf.
for ideal schematic plz refer connection from datasheet.
 

Yes i have installed FT232BL driver. I have other device with this IC and it works fine. I dont know. Maybe that FT232BL is wrong?
