I need to telnet inside my Linux phone (Motorola A780) and my Zaurus. I put the
phone to "modem mode", I connect the usb cable, and the system can see the
device on /dev/ttyACM0 just fine. I load the "usbnet" module, and next I need to
ifconfig the usb0 interface. Well, that's the problem, there is no usb0 device
to be found. Ifconfig says it doesn't exist, but users of older kernels are
having that interface created. With more recent kernels on both my distros, this
interface is not created automatically for me, so I can't continue with ifocnfig
usb0 and then telnet in the phone. I also tried plugging and unpluggin the phone
and I also tried: echo 'AT+MODE=99' > /dev/ttyACM0
which disconnected and connected back the device, but no luck. Usb0 (or
equivelant) is nowhere to be found.
Never mind, it worked after loading the cdc-acm module...
