Hi. I have 3 separate boards each one with a USB-UART converter. Each USB-UART converter handles 4 independent bidirectional UARTS. In a PC I see each UART as COM1, COM2, COM3, etc. When I plug a second board, I see COM5, COM6, etc.... until COM12. All OK. The thing is that I have to use a USB HUB to enter with the three USB interfaces and get out with only one. I think the TUSB4041I can solve my problem but I'm not sure if the enumeration of each downstream device always (between power on resets) is the same. This is important because I have an application that looks for COM 7 for example, and the COM 7 must be always the same physical UART. Also, if I disconnect the device of COMS 5,6,7 and 8 and make a power on reset, I will expect that the other COM numbers did not change...but I don't know.
I hope you can understand my problem. Thanks and regards
SR
