Linksys WUSB54GCv3

[Eric Spreen]

Hello all,

First of all, I'm not exactly a Linux guru, so please don't be too
harsh ;)

I have recently bought a wireless USB NIC: The Linksys by Cisco WUSB54GC
version 3. I would like to use it on a Debian system. I have found some
docs telling me that I should use the Ralink rt73usb driver, because it
is build upon the RT2501USB chipset. Other documents [1] told me it uses
the RT2800U chipset and that I should use the rt2870sta drivers instead.

I have tried both these drivers, following these [2][3] tutorials on the
Debian wiki. However, when I connect the USB adapter, iwconfig doesn't
show any other devices than my default lo and eth0 interfaces.
Therefore, I think the drivers are not loaded properly. (I have tried
loading the modules using modprobe) Does anybody have a solution to this
problem?

Greetings,
Eric Spreen

PS When using the rt73usb module, I had kernel version 2.6.26-2-686.
When I tried the rt2870sta module, I installed version 2.6.29-bpo.2-686.
Furthermore I'm using a standard Lenny distribution, without a graphical
interface. (I'm planning to install LXDE, because I want a lightweight
GUI)

The proper attitude always helps.

What's the output of lsusb, and "lsusb -vs XXX:YYY"?

Neither am I (a guru) ;)

Install the firmware-ralink package from non-free and the kernel should
pick the right driver (if available) automagically.

Well, that's apparently the problem, because the kernel doesn't. Even if
I load the correct module (rt2870sta, that is) using modprobe, the
device doesn't work properly. I think firmware-ralink is not yet
compatible with version 3 of this device.

However, I have managed to get this thing working using ndiswrapper with
a slight modification. When using the version provided by Debian, you'll
get an error saying that a symbol is undefined
(MmGetSystemRoutineAddress). Dirk Schwendemann posted a remedy for this
on the ndiswrapper homepage [1]. Just add this in the source file
ntoskernel.c:


wstdcall void* WIN_FUNC(MmGetSystemRoutineAddress,1)
(struct unicode_string *name)
{
struct ansi_string ansi;
if (RtlUnicodeStringToAnsiString(&ansi, name, TRUE) ==
STATUS_SUCCESS) {
WARNING("MmGetSystemRoutineAddress: %s", ansi.buf);
RtlFreeAnsiString(&ansi);
}

Then build the module and load it, load the XP driver on the provided CD
and it should work. I hope I am helping somebody :)

Which version of firmware-ralink do you have? RT2870 Firmware was added
to that package in version 0.17.

Ah, then that's the problem. I've got version 0.14+lenny1. I see version
0.17 is available as a backport. I'll try that asap. For now,
ndiswrapper also works perfectly. By the way, the workaround for the
MmGetSystemRoutineAddress bug I posted saturday is incorrect. Of course,
there should be a return statement :)

wstdcall void* WIN_FUNC(MmGetSystemRoutineAddress,1)
(struct unicode_string *name)
{
struct ansi_string ansi;
if (RtlUnicodeStringToAnsiString(&ansi, name, TRUE) ==
STATUS_SUCCESS) {
WARNING("MmGetSystemRoutineAddress: %s", ansi.buf);
RtlFreeAnsiString(&ansi);
}

return 0;
}
