Comment 20 for bug 330934

The Dell BT 370 still doesn't work after resume from suspend on karmic:
$ hcitool scan
Device is not available: No such device

/lib/udev/rules.d/62-bluez.rules contains:
ACTION=="add", ENV{ID_VENDOR}=="413c", ENV{ID_CLASS}=="mouse", ATTRS{bmAttributes}=="e0", KERNEL=="mouse*", RUN+="/usr/sbin/hid2hci --method dell -v $env{ID_VENDOR} -p $env{ID_MODEL} --mode hci"

Doing it manually works:
$ sudo hid2hci --method dell -v 413c -p 8158 --mode hci
Attempting to switch device 413c:8158 to HCI mode was successful

Enabling and disabling the killswitch after resuming from suspend also sets the bluetooth module to the right mode.
