This one clearly has counterfeit chip but seems to work correctly:

The one that Peter suggested is RS232, not RS485. You can also get USB-RS485 there, but looking at provided schematics it seems to be lacking line-biasing resistors (which are present on chinese board), which are needed for proper operation.

So as I see some converters have support for both standards and some have support for only rs232. In the past I saw such situations when somebody connects converter via DB9(only 3 pins) to RS485. So at this moment all is clearWink
