Arend and Franky,
I recently purchased a Belkin N600 DB USB dongle on Ebay. I wanted to get the
model with a Realtek RTL8192DU chip. Instead I got a version with a Broadcom
chip, which lsusb identifies as
Bus 001 Device 005: ID 050d:615a Belkin Components F7D4101 / F9L1101 802.11abgn
Wireless Adapter [Broadcom BCM4323]
I have since acquired a different device with the Realtek chip, thus I could
return the Belkin device; however, the cost was minimal and I will keep it if
there is a driver for it. Is it a brcmfmac device that is not yet in the device
tables, or is it some other sort of unit that may never be supported under Linux?
Thanks,
Larry

Thanks for the info. I will try to return the device.

It has been suggested before (by you if I recall correctly). Howeverm
the number of chip programs is extensive and it is hard to find out
which went into production and are available to end-users. So we decided
only list what we know.

The bcm43143 (and bcm43242) support is in the driver, but the firmware
for these chips have not been released yet. With that I mean not
released at all so we can not submit any firmware for those chips to the
linux-firmware git repository. Consequently, it does not make sense to
list them on wireless.kernel.org.
Thanks for the kernel version suggestion. I will add that info although
there is always compat-wireless...eh...compat-drivers ;-)

Hi Larry,
I went digging and this chip requires a different driver model
(basically a split stack between host and dongle). This model is being
abandoned for newer chips so we decided not to support it in mainline linux.

What do you think about listing not supported chipsets on your
brcm80211 wiki page? Thay way users will get clear overview of this
situation. I think I already heard similar answer about BCM43236 V2
(found by Hauke in his router).
Btw. your http://wireless.kernel.org/en/users/Drivers/brcm80211
doesn't say anything about BCM43143, which (I believe) is supported by
brcmfmac.
Oh and one more thing: I believe putting minimal kernel version
requires is also a good idea. Something like:
"BCM43143 - supported since 3.123"

As I just got hold of a Realtek RTL8192DU device (DeLock 88540[1]), I'm
curious if you had a go with a driver for this chipset. The vendor
driver seems to have issues with 64 bit operation (and kernel 3.7).
usb 3-1.1: new high-speed USB device number 6 using ehci_hcd
usb 3-1.1: New USB device found, idVendor=0bda, idProduct=8194
usb 3-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-1.1: Product: 802.11n NIC
usb 3-1.1: Manufacturer: Realtek
usb 3-1.1: SerialNumber: 00e04c000001

Stefan,
I have made some progress with the driver merged into staging. In addition, I
have fixed the problems with 64-bit operation and the lack of kernel_thread() in
3.7 for driver rtl8192DU_linux_v4.0.0_5260.20120921. As I'm not sure the list
wants to get the patch, I'll send it separately via private email.
Your tests will be useful as my device has USB ID 0bda:8193.
Larry
