It's not that you cannot do it, you just have to have a blob or dongle in the middle that is going to do the client work for both sides. It's a little more complicated solution, since you have to have an object that can communicate with two hosts. I have not researched A-to-A cables, but I know that they exist and have been used for that purpose.

Can we use A-to-A cable for EHCI host for debugging purposes? If no can you explain me the reason why it cannot be done? Can you propose an alternate idea for EHCI host debugging? -- Regards, Anil Nair -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
