On my Fedora 10 laptop nothing appears to happen anymore when I plug
in the Neo. No messages in /var/log/messages, nothing in dmesg.

I am booting from U-Boot (in NAND) though, the post referenced above
mentions SHR-testing (the distro on the SD I'm booting from) behaving
differently when booted from QI.
I get the same result on my Xubuntu laptop so I fear that something
else got broken with the opkg update, opkg upgrade I performed.
So far I haven't found a description of what is needed on the side of
the FreeRunner itself.
When I check ifconfig -a on the FreeRunner I see an eth0 interface
with no IP address, eth0:avah alias with IP 169.254.7.134 and the
ip link show shows the loopback device and the eth0 interface.
When I check the /etc/network/interfaces it contains a comment right
before the auto usb0 section saying:
# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
ifup usb0 retruns:
ifup: interface usb0 already configured
but ifconfig usb0 returns:
ifconfig usb0: error fetching interface information: Device not found
modprobe g_ether on the FreeRunner fails to locate the module so maybe
some modules are missing? Or is this module no longer needed?
loading the usbnet module on either the Fedora or the Xubuntu laptop
does not help.
One final note: the hardware is fine, when I start FDOM from the
device's main memory it is still recognized.
Thanks in advance.
