The firmware is the missing part to support this device in kernel 3.16.

Unless we can get BCM43142A0-0a5c-216a.hcd from Broadcom, what we can do now is just like what @Pilot6 said in the previous comment. If anyone wants to convert an hex file to an hcd one, here's how:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1065400/comments/11
And note that please use BCM43142A0-0a5c-216a.hcd instead of fw-<vid>_<uid>.hcd, and copy the file to /lib/firmware/brcm/ instead.
