Hi,
I'm working on a set-top-box that needs a wireless network using an
usb wireless adapter such as the d-link dwl-122 that is supported
under Linux.
I have a kernel 2.6.23.17, libc 2.6 and udev 129. For several reasons
I cannot upgrade the kernel :(
My problem is that after compiling the kernel with all the necessary
wireless modules (like mac80211), compiling and insmoding the usb
wireless driver (rt73), copying its fw, and connecting the usb
adapter, I have the following behaviour:
There isn't any change in /sys/. I would expect a new dir in
/sys/class/net (something like /sys/class/net/wlan0).
# ls /sys/class/net/
eth0 lo
If I write a 00-test.rules, when I connect the usb adapter it matches
and calls the test.sh script.
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="07d1",
ATTR{idProduct}=="3c0f", RUN+="/usr/bin/test.sh"
so I think the kernel is sending the event to udev, but I don't see
any net iface.
iwconfig doesn't give any wireless interface:
# iwconfig
eth0 no wireless extensions.
lo no wireless extensions.
lsusb and cat /proc/bus/usb/devices give the right ouput:
# lsusb
Bus 001 Device 011: ID 07d1:3c0f D-Link System
...
# cat /proc/bus/usb/devices
T: Bus=01 Lev=02 Prnt=02 Port=02 Cnt=01 Dev#= 11 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1

E: Ad=81(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=01(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=03(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=04(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=05(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=06(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
Here's the output I get when I connect the usb wireless adapter with
the kernel's usb debugging active:
usb 1-1.3: new high speed USB device using stm-ehci and address 10
usb 1-1.3: Product: 11g Adapter
usb 1-1.3: Manufacturer: Ralink
usb 1-1.3: SerialNumber: 1.0
usb 1-1.3: configuration #1 chosen from 1 choice
Other devices like usb mass storage devices work smoothly as well as
usb mice and keyboards. This happens with the usb wireless adapter
that I have tested.
I'm not sure if the problem is because I have old versions of
udev/kernel/libc or if I'm missing something.
Any ideas/hints?
Thanks in advance!
