2008-10-06[Bluetooth] Add reset quirk for A-Link BlueUSB21 dongleMarcel Holtmann
The new A-Link Bluetooth dongle is another one based on the BCM2046 chip from Broadcom and it also needs to send HCI_Reset before it becomes fully operational. Without the quirk it will show a lot of I/O errors. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-10-06[Bluetooth] Add reset quirk for new Targus and Belkin donglesMarcel Holtmann
Targus and Belkin have come out with new Bluetooth 2.1 capable dongles using the latest BCM2046 chip from Broadcom. Both of them are so called HID proxy dongles and they need to send HCI_Reset before they become fully operational. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2008-10-06[Bluetooth] Fix double frees on error paths of btusb and bpa10x driversMarcel Holtmann
The transfer buffer of an URB will be automatically freed when using the URB_FREE_BUFFER transfer_flag. So the extra calls to kfree() will cause a double free.

2008-09-23[Bluetooth] Fix USB disconnect handling of btusb driverMarcel Holtmann
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.

2008-09-23[Bluetooth] Fix wrong URB handling of btusb driverMarcel Holtmann
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.

2008-09-23[Bluetooth] Fix I/O errors on MacBooks with Broadcom chipsMarcel Holtmann
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 <marcel@holtmann.org>
2008-08-18[Bluetooth] Add SCO support to btusb driverMarcel 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.

2008-08-07[Bluetooth] Add full quirk implementation for btusb driverMarcel Holtmann
This implements all the quirk handling from the hci_usb driver to the new btusb driver. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-10-22[Bluetooth] Add generic driver for Bluetooth USB devicesMarcel 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 <marcel@holtmann.org>
