[Bug 1315290] [NEW] Broadcom BCM2046 Bluetooth not detected

Public bug reported:

The bluez package provides some udev rules in /lib/udev/rules.d/97
-bluetooth-hid2hci.rules to switch some Dell devices into hci mode. The
same is necessary for Broadcom BCM2046 based devices.

To get bluetooth working on my Lenovo Ideacentre B320 I added the following rule to my local rules:
#udev rules für Lenovo Ideacentre Bluetooth

ACTION=="remove", GOTO="idea_end"
SUBSYSTEM!="usb", GOTO="idea_end"

# Variety of Broadcom Bluetooth devices - match on a mouse device that is
# self powered and where a HID report needs to be sent to switch modes
# Known supported devices: 0a5c:4503

ATTR{bInterfaceClass}=="03", ATTR{bInterfaceSubClass}=="01", ATTR{bInterfaceProtocol}=="02", \
  ATTRS{bDeviceClass}=="00", ATTRS{idVendor}=="0a5c", ATTRS{bmAttributes}=="c0", \
  RUN+="hid2hci --method=dell --devpath=%p", ENV{HID2HCI_SWITCH}="1"

Please add this rule to 97-bluetooth-hid2hci.rules
