Arduino Pro Mini Software USB

Hi all,
On the Internet a lot written about the soft-USB, but little has been written about this on the Arduino Pro Mini and/or Atmega328. And even less about this soft-USB to 16MHz.
As a result, the most appropriate option turned AVRDoper, assembled under metaboard. There Atmega168 and 16MHz crystall.
Write atmega328p instead atmega168 in Makefiles, i make firmware, flash this... and got a "USB Device Not Recognized". And I get this message with any firmware about USB

Dear friends, please tell me where to get the finished version USB firmware (with sources of course) for the Arduino Pro Mini 5v/16MHz//Atmega328p

Me need a connect arduino to PC via usb (and virtual com port on system) for sending info from arduino to pc.
Regrads,

I am not entirely sure what question you are asking, but I have a 328 based Pro Mini (16V, 16 MHz) and connect to USB with a device like this http://www.ebay.co.uk/itm/FT232RL-FTDI-USB-to-TTL-Serial-Converter-Adapter-Module-fr-Arduino-Mini-3-3-5V-/191081981731.

In use it is indistinguishable from using an R3 UNO once the correct board is selected in the IDE.

no, i need direct connect arduino to usb. and present it in pc as com port wthouy a usb-uart adapter.
example as V-USB
in my Arduino pins rx/tx do not work :slight_smile:
