 |
|
Since linux-wlan-ng currently does not work for me I switched over to ndiswrapper.
My usb stick (dwl122) is supported and is working but sometimes - not always - when I plug out the stick (and the hotplug event should remove the module) the complete usb system is crashing.
The ndiswrapper module is still loaded and usb does not recognize any new device that is being plugged in.
There is no hint in dmesg
| Code: |
<-- when I plug it in -->
usbcore: registered new interface driver ndiswrapper
ADDRCONF(NETDEV_UP): wlan0: link is not ready
ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
wlan0: no IPv6 routers present
<-- when I disconnect it -->
usb 2-1: USB disconnect, address 9
|
After that there is no message when I plug in another usb device. Nothing to see in any log file.
When I manually try to remove ndiswrapper I get
| Code: |
usbcore: deregistering interface driver ndiswrapper
|
in dmesg but rmmod hangs forever (and can't be killed with -9)
I have to restart the machine to get usb back.
Out of 5 tries this may happen 2 or 3 times...

Bump...
I tried to solve it by not removing the module when removing the stick - but it just happened again.
So it seems to me that ndiswrapper closes things uncleanly and blocks itself and the usb system.
As I can not remove the module (rmmod hangs) I cannot use usb as modules and 'restart' it by un- and reloading it - I have to reboot
