USB interface, BCU2 supporting FT1.2

[Warichet]

Hi,

I'm looking for a USB interface, must be BCU2 supporting FT1.2.
I searched the forum and just found
USB (BJ6123) funktioniert nicht mmmm, no reply
Are there other suppliers ?
Ideally, it would be a dual RS232/USB I/F, but the one from Eibmarkt is not for Din rail (not sure this thing is working fine).

Thank you for your suggestions
