[maemo-developers] [maemo-developers] Adding USB-EtherNet Support

[From: etienne at solve400problems.com]

I am trying to get a Linksys USB100M USB-EtherNet adapter working. I have
the power injection working and the 770 is correctly working in USB host
mode.

The USB100M uses the RTL8150.ko on my laptop, so I assume that I need to get
this object compiled for the 770. 

I compiled this module and copied it to the 770. Then I do the following:

Nokia770-26:~# insmod rtl8150.ko
Using rtl8150.ko

Nokia770-26:~# dmesg
[68148.108642] drivers/usb/net/rtl8150.c: rtl8150 based usb-ethernet driver
v0.6.2 (2004/08/27)

>> Plug-in USB100M

The last sequence of messages just keep repeating and the 100MB led on the
USB100M flashes on and off.

When I execute ifconfig eth0 up the 770 will reboot with /proc/bootreason
32wd_to.

Can anybody please offer some advice?
