Re: h5550 wifi power down

I see what I did wrong. In order to remove the driver one needs
1. to establish the link-level connection (iwconfig eth0 ...), too bad if
your access point is not configured, then you'll fail this step.
2. to configure the interface (ifconfig eth0 up)
Note, the IP connection is not necessary. I did not configure the IP
address. On the other hand this does not hurt, the IP can be
either configured or not.
3. to stop the interface (ifconfig eth0 down)
4. ...and only then the module can be removed (rmmod usbvnetr)

Is it the fault in the driver that it cannot be removed without the above
hassle? I am experimenting now checking battery life in the sleep mode.
The first impression is that without the driver the consumption is lower.
Still the unit looses about 30% in 20 hours and I am using the expansion
pack with a second battery.
