I am really unhappy with USRs support for Linux. Most of the USR card do not work out of the box while other cards seem to be better supported. It seems from what I read that it is all realted to the openess of the TI chipset. Anyway, I wonder if somebody can help me.

1) I installed linux-wlan-ng-0.2.1-pre15 which seems to work fine until. I am not sure if there is a problem here.

2) dmesg has the following output at the end

3) /etc/rc.d/init.d/wlan restart produced the following error
Shutting Down WLAN Devices: Shutting Down WLAN Devices: wlanctl-ng: No such device
wlan0: unknown interface: No such device
Starting WLAN Devices: /lib/modules/2.4.20-8/net/prism2_pci.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-8/net/prism2_pci.o: insmod /lib/modules/2.4.20-8/net/prism2_pci.o failed
/lib/modules/2.4.20-8/net/prism2_pci.o: insmod wlan0 failed

4) /sbin/lsmod |grep prism2 produced nothing

Does anybody know what I can do?

Thanks,
Sam

As root, just issue the command "/etc/init.d/wlan stop" first. You apparently have already tried to install and configure wland (a previous version?), and now you're trying to install again. In order to "make install" successfully, you need to make sure that the wland process is no longer running.

And yeah, USR sucks but hey, I got their card for free.
