My reading of the USB specification is that the new address takes effect after the SET_ADDRESS status stage is "completed successfully", which means after the ACK for the ZLP is received by the device. What behavior should be expected if that ACK is sent by the host but lost before it is received by the device? The host believes it has successfully updated the devices address, but the device must continue to respond to the old address. Does the host somehow detect this (perhaps because it can no longer enumerate devices?), and what should it do if it does detect it? Rob.
