Sending an HCI_Reset to a CSR device running firmware earlier than 12.0 will cause the device to perform a full system reset. This means that the host transport will be reset (USB devices will drop off the bus and reattach, BCSP devices will need to perform link establishment) and it means that settings will be reloaded from persistent store (so the baud rate will reset). Firmware version 12.0 and later are better behaved and will reset all the LM and LC settings (drop all links etc.) but leave the host transport up and running.
