did you install the firmware-realtek package as slh suggested?

Are you sure to even have the required firmware (#588142)?
      Code:
$ cd /tmp/
$ wget ftp://ftp.dlink.com/Wireless/dwa130_revC/Drivers/dwa130_revC_drivers_linux_006.zip
$ unzip dwa130_revC_drivers_linux_006.zip
$ su

# mkdir /lib/firmware/RTL8192U
# cp ./rtl8192u_linux_2.6.0006.1031.2008/firmware/RTL8192U/*.img /lib/firmware/RTL8192U/
(reload the module/ tell it about the new ID again).
      Code:
f0b36fa2fa5f89e8246a9e353b990952 */lib/firmware/RTL8192U/boot.img
7f06fe4c1d4098e0c363c0e06cb991ee */lib/firmware/RTL8192U/data.img
5b998bb6dcba47221abe3468361a0158 */lib/firmware/RTL8192U/main.img
If you can confirm your device to be supported by r8192u_usb, I'll take care that your ID gets added to the kernel (likewise an according MODULE_FIRMWARE() definition).

Ahhhh -- I had the ...SU directory, not the ...U directory. Let me try it.

As far as I can tell, the firmware is right, per the wiki and your instruction:

      Code:
root@ambucsbox:/lib/firmware/RTL8192U# md5sum *.img
f0b36fa2fa5f89e8246a9e353b990952  boot.img
7f06fe4c1d4098e0c363c0e06cb991ee  data.img
5b998bb6dcba47221abe3468361a0158  main.img


The module is loaded:
      Code:
root@ambucsbox:/# lsmod
Module                  Size  Used by
.
.
.
usbcore               117921  4 r8192u_usb,uhci_hcd,ehci_hcd


The ID is loaded:

      Code:
root@ambucsbox:/# echo -n "050d 2103" > /sys/bus/usb/drivers/rtl819xU/new_id
root@ambucsbox:/#


ceni can now see the device as:

      Quote:
wlan1 wireless 00:e0:4c:00:00:02 rtl819xU Realtek Belkin Wireless


However the configuration fails:

      Code:
root@ambucsbox:/# ceni

wpa_supplicant: /sbin/wpa_cli daemon failed to start
run-parts: /etc/network/if-up.d/wpasupplicant exited with return code 1

Press Enter key to continue ...


and as previously discovered, the problem was shown to be:

      Code:
root@ambucsbox:/# ifconfig wlan1 up
SIOCSIFFLAGS: Resource temporarily unavailable


and the dmesg story is exactly as shown above -- failure of firmware to load.

I'm confused. I guess we still don't know which is the correct driver, for sure.

@DeepDayze, I did learn how to install the kernel source correctly under /usr/src. I could edit a driver source file to add the Belkin n300 Micro device, but then I would need guidance to compile it. But I wonder which driver is the correct one?

You can (temporarily) inject new IDs through the method depicted above, recompiling the kernel doesn't change that.

My logic may be flawed, but it seems like this:

- because it is a b/g/n USB device, according the wiki the 3 possible drivers are r8192u (supersedes r8192s_usb), r8192u_usb, and rtl8192cu.

- r8192u driver loads, and ID can be loaded, but ceni does not find any wlanx interface.

ifconfig wlan0 or wlan1 up reports "no such device found"

- rtl819cu driver loads, but loading the ID crashes the kernel

- r8192u_usb driver loads, and ID can be loaded, and wlan1 interface is available, but the firmware loading fails.

So (depending on the accuracy of the wiki), it seems there is something missing from the information. This is not really a brand new cutting edge product -- one would think there should be more information about it, but my google-foo is not finding it. If there's more I can do to help crack the case and enable it to be supported by the aptosid kernel, I'm happy to do what I can.

EDIT: This factoid indicates the chip is the RTL8192CU (my n300 Micro is model F7D2102).

Could the firmware loading failure be a bug?

I had a Micromax USB modem, never looked at what it had inside,
it is seen basically as a serial device, so it should work with
Kppp for basic operation. Just choose the right port.

Since there is a lot of discussion on it already, hopefully I am not on wrong track.

If the Debian "tidbit" is correct, meaning the needed driver is rtl8192cu, then the problem is that inserting the device ID causes a kernel oops.

Please try it with the device unplugged and plug it in after new_id.

With the adapter not plugged, the module and ID were loaded with no problem. Upon plugging in the adapter, it instantly crashed:

http://pastebin.com/RWuKm18z


EDIT: For comparison purposes, I tried the device and driver on my Intel motherboard:

      Code:
Host/Kernel/OS  "susansid" running Linux 2.6.39-3.slh.2-aptosid-amd64 x86_64 [ aptosid 2011-01 Γῆρας - kde-lite - (201102051540) ]

After loading the rtl8192cu module, and loading the ID, I plugged in the device. It did not crash the system, but I got kernel messages in the terminal that I was using:
      Code:

No, I have that one pinned at 2.6.39, because my wife needs the Windows VM which is VMware. VMware hasn't heard about Linux 3.0 yet Rolling Eyes

But I'm running the 3.0 kernel elsewhere with no issues.

Please test linux-image-3.0-0.slh.5-aptosid-{686,amd64} 3.0-5, it includes your USB ID for testing.

With the new kernel installed on the Dell Optiplex GX270, the driver modules are loaded automatically.
      Code:
root@ambucsbox:/home/guest# lsmod
Module                  Size  Used by
rtl8192cu              86576  0
rtl8192c_common        52328  1 rtl8192cu
rtlwifi                82992  1 rtl8192cu
mac80211              188982  3 rtl8192cu,rtl8192c_common,rtlwifi
cfg80211              138597  2 rtlwifi,mac80211
cpufreq_stats           2257  0
.
.
.
usbcore               117921  5 rtl8192cu,rtlwifi,uhci_hcd,ehci_hcd


I load the new ID and there is no kernel oops or any error:
      Code:
root@ambucsbox:/home/guest# echo -n "050d 2103" > /sys/bus/usb/drivers/rtl8192cu/new_id
root@ambucsbox:/home/guest#

Unfortunately, there is also no wlan ...
      Code:
root@ambucsbox:/home/guest# ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device
root@ambucsbox:/home/guest# ifconfig wlan1 up
wlan1: ERROR while getting interface flags: No such device
root@ambucsbox:/home/guest# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

First attempt was booting with the USB device installed, second attempt was hot plugged. I tried front USB connector and rear connector. That's the test report, unless there is more I can do. Thanks for working with it.

Edit: Also checked it on my Asus desktop box -- same result.
      Code:
root@aptosidbox:/home/don# infobash -v3
