I'd like to, especially since it theoretically allow more powerful phone
interactions but I can't get it to work.
usb/* permissions are ok, message is sent, but timeouts occurs and no
response arises.

Using strace and given that the correct bus is the usb/002/002
I should first note that, very strangely since I set the gnokii "port"
setting, all usb ports are tried in both O_RDWR then O_RDONLY, and all
fail (except 002/002) on EACCES because udev # didn't set them to the
"audio" group.
Anyway...

Remember that I use a "DKE-5" cable (more exactly a dumb
USB<->micro-USB cable) connected to a 7230 phone.

In my case, --getfile (at least) worked using cdc-phonet, didn't test
the other twos
