Apparently in 14.10 the .hcd file needs to be /lib/firmware/brcm. Here is the .hcd file for the IOGEAR GBU521 (0a5c:21e8). Place it in /lib/firmware/brcm/BCM920702 Bluetooth 4.0-0a5c-21e8.hcd (Yes including the spaces in the file name)
modprobe -r btusb modprobe btusb Looks like it is successfully loading the firmware [513973.825046] Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=153a lmp_ver=06 lmp_subver=220e [513974.598398] Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=153a lmp_ver=06 lmp_subver=220e If you have a different model you can find what the filename should be from syslog [513871.502139] Bluetooth: hci0: BCM: patch brcm/BCM920702 Bluetooth 4.0-0a5c-21e8.hcd not found Note: the attached .hcd only works for the IOGEAR GBU521. You'll have to find and convert the .hex file for your specific model. ** Attachment added: "BCM920702 Bluetooth 4.0-0a5c-21e8.hcd" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1065400/+attachment/4292669/+files/BCM920702%20Bluetooth%204.0-0a5c-21e8.hcd -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1065400 Title: Support for loading Broadcom bluetooth firmware Status in linux package in Ubuntu: Fix Released Status in linux source package in Precise: Fix Released Status in linux source package in Quantal: Fix Released Status in linux source package in Raring: Fix Released Status in linux source package in Saucy: Fix Released Bug description: Broadcom bluetooth chips require a tool called patchram uploader [1] to load firmware. This applies to at least BCM20702 and BCM43142. Although some of the devices have an OTPROM that contains required firmware, but it is found that these devices would not have HFP/HSP support unless a upgraded firmware is loaded via patchram uploader. This tool requires hci device to do the firmware loading, but this may cause some race condition between patchram tool and bluetoothd or something that also works on hci interface. Also it needs some hooks to make firmware loads after bootup, s3, s4, rfkill, and device hotplug events. Implement this loader in kernel module would make things more easier.
