I'm connecting my samsung A620 phone to my computer via USB to use the
internet access. When I connect it, the cdc_acm module loads. From
what I've gathered from searching is that it should create a device
called ttyACM0 in the device directory. I can't find it.
I did get it to work temporarily by doing this:
ls /sys/bus/usb-serial/devices/
ttyUSB0 ttyUSB1 ttyUSB2 ttyUSB3
cd /dev
mkdir usb
mknod /dev/usb/ttyUSB0 c 188 0
mknod /dev/usb/ttyUSB1 c 188 1
mknod /dev/usb/ttyUSB2 c 188 2
mknod /dev/usb/ttyUSB3 c 188 3
I did cat /dev/usb/ttyUSB# until it did not say "no device ..."
Then I put the device in my pon script and I was able to connect. But
when I rebooted, all of the devices disappeared.
I think that when I plug in the phone, udev should create a device
somewhere. Where does it create it?
