rtl8187 not handling my usb card

rtl8187 not handling my usb card

[Viktor Ilijašić]

Hi all.

Sorry if I'm not posting this properly, my first time here.

I have what might be a bug to report:

My Realtek 8187 USB wifi card is not being handled by rtl8187 module.

I am using Ubuntu 8.10, and module from Jan 29th that is (presumably)
supplied by Ubuntu package linux-backports-modules-
intrepid is not handling the card, as well as the one I built myself
from (git?) sources, dated Feb 15th.

I can properly load the module rtl8187 (both already mentioned
versions), but when I insert the USB card, nothing happens. See logs
at the bottom.

To properly load two versions I had to correspondingly rename
mac80211.ko and cfg80211.ko, since there were errors reported (unknown
symbols, unable to load, etc). Since I can properly load the modules,
dependencies are not the problem. Unless there is some other *.ko that
I need to rename?

The card is AirLive WL1600USB, PCI/USB ID 1b75:8187,
url: http://www.airlive.com/product/product_3.jsp?pdid=PD1223473034861

I somehow have the feeling that the PCI/USB ID of this card is
unrecognized by the module (if the module even recognizes hardware
only by it's ID), since this is rather obscure ID (google only returns
2 results for that ID). I'm no expert, I might be wrong.

I'd like to get it working with native drivers if possible. Didn't try
ndiswrapper yet, and I'd rather if that were not my only option.

If any more info is needed, please, feel free to ask.

You might try applying the patch below and rebuilding your kernel.
Does that get the driver to recognize the device?

The driver for USB devices is selected from the ID's, just as it is wit=
h PCI
devices.

Please send the details for your device as output from the 'lsusb -v' c=
ommand. I
don't need the data for any other USB stuff, just the 8187. Once I have=
 that
info, I will send you a test patch for your sources.

When you do that, does it work?

Hiya,

A quick search on google shows Airlive hosting a linux driver here:

http://www.airlive.com/support/support_3a.jsp?pdid=PD1223473034861

I had a quick look  and indeed it looks like the realtek vendor driver
(or a variant of) for 8187L.
Note that this is for reference, since we all know the vendor driver
has some issues with the latest wireless stack, etc.

Once I get confirmation from the OP that his device works, I have a patch with a
total of 6 new ID's for rtl8187. Four of them came from the .inf file
accompaning the Windows version of the RTL8187L driver.

Re: rtl8187 not handling my usb card

[Viktor Ilijašić]

Hi all.

Yesterday evening I tried John's patch (I manually added those two
lines to the source), and the driver properly loads and it seem to
work.

However.... it would seem that my card died some time in the last few
days. It works for about 10-15 seconds after i plug it in, and then
"dies". I'd say that when it gets warm, it's out of the game.

In Linux after i plug it in, it works just enough time to:
1. detect networks in ubuntu network manager (and return a nice scan
result with iwlist wlan3 scan)
2. starts to connect to my network (and reaches random points in connecting)
3. stops responding altogether, cannot connect, no more results with
iwlist scan, etc.

I noticed this exact behavior in windows too, yesterday morning,
before I tried these patches, so linux driver is DEFINITELY not to
blame.

In windows it very shortly detects available networks, starts to
connect and very soon stops responding and finding networks.

I'll return it to shop to be replaced, and I'll report back when I get
one that works properly.

Also, Larry, I took lsusb -v output during those first few moments
while the card operates properly, hope it helps:

Hin-Tak, I did see the AirLive linux reference driver, but didn't even
want to try that, unless my only option left was ndiswrapper. I know
those manufacturer's "drivers" usually cause more frustration than
use.

Thanks all for your time and help.

That output confirms that it is an 8187, not an 8187b.

I also had a Realtek device fail, but after replacement, all has been w=
ell.

Thanks for testing.

Re: rtl8187 not handling my usb card

[Viktor Ilijašić]

Hi, all.

I received a new card, after the old one died, and I'm happy to report
that the card works properly under Linux with my patched version of
the driver (the patch was only to add the USB ID). I see that the
patch was already submitted to the kernel while my card was being
replaced.

Thanks all for your work and help.

You are welcome. Thanks for reporting the new ID. That patch has been a=
pplied to
2.6.29-rcX and will appear in the next releases of 2.6.{27,28}.Y.
