(I haven't used any android phone).
Yes. You have to enable tethering mode as needed on the USB port. For the record, my device is running Android 2.2 (Froyo). With tethering mode DISABLED the device presents one product ID. This is where the mass-storage device shows up. As I originally mentioned there is also a umodem device at this point that is usable with PPP (this is not tethering mode in the Android sense where the Android device acts as a NATing router and dishes out IP address via DHCP). When tethering mode is enabled the device presents a different product ID which is currently undefined in usbdevs so it shows up as ugen. The patch I originally posted at the beginning of this thread defines the ID and enables the device to work with urndis. As a side note, when tethering mode is enabled, the umass and umodem devices are detached. Here is my output from "usbctl -a 4 -f /dev/usb0" with tethering mode enabled. The Android device is plugged into usb0, port 1, addr 4 according to "usbdevs -v". I'll also include an output from usbctl with tethering mode disabled at the end.
