Broadcom Bluetooth [413c:8143] does not work at all

[Po-Hsu Lin]

CID: 201307-13942 Dell Latitude E5540

The Bluetooth can't find any devices.
Error message could be found in dmesg:
[ 98.149145] Bluetooth: can't load firmware, may not work correctly

Note that sometimes it works, but if you disable and re-enable it with the wifi slider (let it reload the firmware), it will stop working.

Steps:
1. Install 14.04.1 + update (3.13.0-37) + proprietary Broadcom driver
2. Try to pair with any other Bluetooth device.

Expected result:
* Bluetooth works well as expected.

Actual result:
* Nothing can be detected.

sadly this broadcom bluetooth device needs firmware to work (lp:1160171).

[Chih-Hsyuan Ho (chih)]

As stated in comment #3, does installing the required firmware fix this issue?

[Chih-Hsyuan Ho (chih)]

It seems that this has been a known issue for all Broadcom BT devices in standard Ubuntu and the issue can be fixed if we simply pack the same solution (brcm installer) into standard Ubuntu. Or users are advised to refer to the instructions given in http://askubuntu.com/questions/533043/bluetooth-not-working-on-ubuntu-14-04-with-dell-inspiron-15-3521 and fix it by themselves.

@chih: Was helping a user in #ubuntu today with the same device ID (413c:8143). But I think I'm a bit confused by this, I'm looking at the upstream source and I see:

$ grep 413c drivers/bluetooth/btusb.c
 { USB_DEVICE(0x413c, 0x8197) },
 { USB_DEVICE(0x413c, 0x8126), .driver_info = BTUSB_WRONG_SCO_MTU },
 { USB_DEVICE(0x413c, 0x8152), .driver_info = BTUSB_WRONG_SCO_MTU },
 { USB_DEVICE(0x413c, 0x8156), .driver_info = BTUSB_WRONG_SCO_MTU },

I don't see 0x8143 product Id listed as a matching USB device? So even if a user were to have the correct firmware in place (the user on #ubuntu did, afaict), btusb won't match. Is this really an upstream bug?

Thanks,
Nish

I found this thread on the Internet:
[PATCH 4/6] Bluetooth: Add support for Broadcom 413c:8143
http://www.spinics.net/lists/linux-bluetooth/msg56348.html

But just like Nish mentioned here, it looks like this was never got merged.
