That's your issue, odds are OS-X doesn't check the bandwidth needed for the devices and tries to use them anyway. We used to do that on Linux many years ago, but had numerous problems with devices so we now follow the specification. It's better to have your device not work at all, than to just randomly not work, don't you think? sorry, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
