Have a look at all the modules provided with firmware 2.0RC3 (modprobe -l)

Three things strike me as peculiar:
1) look at the comments in the usb networking section in /etc/network/interfaces:
# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
auto usb0
iface usb0 inet static
address 192.168.0.202
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.200
It mentions g_ether, but the firmware does not include the module. Maybe they have it in some developer version / kit?
2) pegasus.ko is a module that drives an usb LAN adaptor, if I found that correctly. Makes little sense to me to include that module but not g_ether
3) usbnet.ko is the module that drives the host side of a usb networking connection. So I tried to load this module and network with my Nokia N810 which runs g_ether and USB networks fine with my laptop. The module loads without fault, but the Nokia would not detect a device at the other side, nor would the DR1000 detect the Nokia when I execute "ifup usb0". So it seems that the usbnet module does not work (which is no suprise, as it is supposedly not meant to drive USB OTG devices -- but why is it included here?).
OK, so far some more data. I hope you folk can make good use of it and figure something out. Do let me know if there is more I can do in terms of trying out modules, documenting output etc. And many thanks for your efforts!
