Hi David and Alan, I recently got a question about companion controllers, and their pros and cons. I've heard from various people that companion controllers are a PITA, but I don't know the details. Why are companion controllers difficult to deal with from a software perspective? Big question, I know. :0) Sarah Sharp -- 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
