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.
[For the reasons behind this, see my posting to bluez-devel on 9th
October 2003 in the thread "hciconfig":
