Hi guys! I have the same bug: a headset doesn't work in HSP/HFP mode The firmware(BCM20702A1_001.002.014.1315.1410.hex) is successfully converted via hex2hcd and placed to /lib/firmware/fw-413c_8197.hcd
any hints? I see only these errors in the syslogs: Jan 3 06:14:25 fitz123-laptop bluetoothd[745]: /org/bluez/745/hci0/dev_48_C1_AC_E0_2C_CF/fd0: fd(26) ready Jan 3 06:14:25 fitz123-laptop rtkit-daemon[2277]: Successfully made thread 3043 of process 2262 (n/a) owned by '1000' RT at priority 5.

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.
