The USB transport specification for Bluetooth splits the ACL and SCO
handling into two separate interfaces. In Linux it possible to probe
and disconnect these interfaces independently. So make sure that both
interfaces are tightly bound together.This fixes the suspend regression that some people have expierenced.

The btusb driver contains two typos that result in some buggy behavior,
but the impact is not immediately visible.During initialization the submitting of interrupt URBs might fail and
then make sure to remove the correct flag and not one of the hci_dev
flags.When closing down the interface make sure to kill the anchor for the
ISOC URBs and not kill the interrupt URBs twice.Also cancel any scheduled work when closing down the interface.

The newer MacBooks contain a Broadcom based Bluetooth chip and to make
this work properly, HCI_Reset must be send first. If HCI_Reset is not
used then a lot of I/O errors show up and its triggers packets from
non-existent ACL links.Signed-off-by: Marcel Holtmann

The new generic driver for Bluetooth USB devices was missing proper
SCO support. The driver now claims the second interface for these USB
devices to allow the flow of SCO packets. It also handles switching
of the alternate setting and re-submission of isochronous URBs.The btusb driver is now a full replacement for hci_usb and thus the
experimental tag has been removed and this driver is promoted as
preferred one.Signed-off-by: Marcel Holtmann

This patch adds a new generic driver for Bluetooth USB devices. This
driver is still experimental at this point, but it is cleaner and
easier to maintain than the current Bluetooth USB driver. It is a
much better starting point for power management improvements.Signed-off-by: Marcel Holtmann
