Comment 95 for bug 1065400

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 ...

... and if I now load the (same) firmware manually with ...

   brcm_patchram_plus_usb --patchram ..firmware.. hci0

... i get a working HSP/HFP device!

Can you shed some light in to this? thanks!
