We have a test farm of iPads and iPhones which we are managing through cfgutil. We are trying to update iOS and push new software to around 40 devices, but cfgutil only lists some of them depending on how we connect our USB hub tree. All devices are at the same tree depth, but seems to stop after around 22 devices. All devices happily report when we ls the USB tree so doesn’t seem to be a usb issue. Has anyone else observed a limit on the number of devices before the 127 limit of the USB protocol? The USB tree is uniform and only 3 hubs deep.
