service hciattach "echo usb bluetooth, nothing to do!!' or something like,
service hciattach /system/bin/hciattach -l
# changing user to root from bluetooth is a potential security issue
# service hciattach_legacy is used instead of hciattach because, we dont
# have nodes named ttyHS0
group bluetooth net_bt_admin misc
