Some Ralink WiFi + CSR BT module needs bluetooth radio to be turned on explicitly with bccmd by the following command: bccmd psset -r 0x028c 0x0001 The HCI will be probed successfully, but due to the default OFF state of the radio, no scan or connection can be made. This patch adds the udev rule so that once the HCI is up, udev will invoke bccmd with warm reset to turn on the radio.
