You could see what you can do with this protocol analyser and pattern
generator, or perhaps ask the customer support.

The Cypress EZ-Host (CY7C67300) and EZ-OTG (CY7C67200) also come to mind, for compact, low-cost solutions. They each have two USB SIEs that can each be configured as device or host. They can boot from an I2C EEPROM. The main drawback is that they use the Cypress CY16 core, so there aren't many choices for development tools. On the other hand, they're very inexpensive.

Trouble is his boards are too popular. I just keep ordering what customers request, and hope they come.

Cant you use a usb to rs232 converter, pic, rs232 to usb converter.
You can get them ready made or just use the chips.

IIRC, the device described by the OP, has only one host and one slave device---not the two hosts your converters would require. Mark Borgerson
