Having used several different manufacturer's offerings ( but not for DMX ), I am pretty sure that you are still correct. These all needed custom drivers, which caused no end of problems, so I now use a processor with an integrated USB interface and rely on the standard device class drivers built in to Windows ( and probaby Linux and whatever the Mac OS currently calls itself as well ).

If there is any interest, I could easily knock up a USB to serial chip that is DMX and RDM aware to get around these problems while still being compatible with software that thinks it is driving a COM port. I might even be persuaded to make it open source
