Hi Jesse, >From your message i infer that the firmware load patch is now in the latest raring kernel (3.8.0-27-generic) and hence automatic firmware load should work correctly?
When i put working firmware as /lib/firmware/fw-0a5c_21e6.hcd on my ThinkPad W530 with 0a5c:21e6 / BCM20702A0 Broadcom chip, i get the following syslog messages ...

Can you shed some light in to this? thanks! -- 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: In Progress 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 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.
