Subject: BCM43142 doesn't work

I found a message to this list from 2013 that indicates the BCM43142
chipset should work:
https://marc.info/?l=linux-wireless&m=137223374523831&w=2

However, what happens is:
Feb 04 11:55:50 localhost kernel: bcma: bus0: Found chip with id 43142,
rev 0x01 and package 0x08
Feb 04 11:55:50 localhost kernel: bcma: bus0: Core 0 found: ChipCommon

Feb 04 11:55:50 localhost kernel: bcma: bus0: Core 1 found: IEEE 802.11
(manuf 0x4BF, id 0x812, rev 0x21, class 0x0)
Feb 04 11:55:50 localhost kernel: bcma: bus0: Core 2 found: PCIe (manuf
0x4BF, id 0x820, rev 0x16, class 0x0)
Feb 04 11:55:50 localhost kernel: bcma: bus0: Core 3 found: UNKNOWN
(manuf 0x43B, id 0x368, rev 0x00, class 0x0)
Feb 04 11:55:50 localhost kernel: bcma: bus0: Bus registered

Nothing else in the logs, no devices created. Am I missing something
like firmware? I would prefer to not have to use a 3rd party driver or
worse, ndiswrapper. This is in an HP laptop.

Thank you, that makes sense. So I will need a 3rd party driver after
all. Unfortunately, the wireless chipset is not one of the specs listed
in most stores.

Which means bcma (bus!) supports BCM43132. It detects bus (!) devices
correctly and registers them. There is no driver supporting wireless
device found on this chipset.

It's a bit like having support for PCI bus. You still need driver for
various devices that can be found/connected to such bus.
