They are the Box-USB. Can run HDDs and CD-ROM's. $79 a piece.
Also, a USB Floppy.. powered by the USB port itself. $44 a piece.
I have both of these products. I opened up the IDE box and the adapter is made by a company called Dura Micro, Inc. They are in Chino, CA and their number is 909-613-1318.
No clue as to the FDD controller.
