With brcm_patchram_plus_usb and hex2hdc I managed to get HFP/HSP on my laptop working (no sound/mic before) using BCM20702A1_001.002.014.0449.0775.hex patchram. However after copying fw-04ca_2003.hcd into /lib/firmware/ and rebooting it doesn't loads patchram and I have to do it manually again.
I'm running Ubuntu-Raring with 3.8.0.30.48 kernel. ----- usb-devices: T: Bus=01 Lev=02 Prnt=02 Port=05 Cnt=02 Dev#= 4 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.)

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.
