 Posted: Tue Jan 13, 2009 8:39 pm Post subject: Usb wlan only works after unplug / plug usb cable |
 |
|
Using Linksys WUSB54GSv2 using drivers from stock kernel gentoo-sources-2.6.27-r7
Built all drivers as modules, and loaded usbnet, rndis_wlan, usbnet, cdc_ether and rndis_host,etc.
will see no device
will return nothing as well.
Now, if I unplug usb cable and plug it back in, the device will be seen by the system and becomes fully operational.
I can bring it up
Associate with the wireless router
| Code: | | wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -B |
and get an ip from dhcp server
Is there any way to automate it and assign to default level?
Or at least I can write a script and execute it on boot (put it to local).
But how to emulate plug /unplug of the usb cable?

What happens if you just reload the modules?
modprobe -r bahbah
modprobe bahbah

and
| Code: | ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device |
after plug /unplug

Weird. Can you force the module unload? modprobe -rf or something like that.
And make sure to ifconfig wlan0 down and /etc/init.d/net.wlan0 stop

What is the result of:
| Code: |
lsmod | grep usbnet |
Wonder why the module in use is...maybe it is used by another module?
