sounds like you need to add the product/vendor IDs to the u3g_dev table in
u3g.c -- if it works then you can proceed to pppd on the tty it attaches.

probably the manpage could be improved to suggest that other adapters may
be supported and that adding the vendor/product ID may be necessary

starting pppd on the tty is pretty simple, I have the following three
files

=== /etc/ppp/options

noauth

=== /etc/ppp/peers/hsdpa

/dev/ttyHS0.08
115200
connect "chat -V -f /etc/ppp/chat.hsdpa"
local
crtscts
defaultroute
updetach
debug
noccp
linkname HSDPA
usepeerdns
novj

=== /etc/ppp/chat.hsdpa

#!/usr/sbin/chat -V -f
#
# HSDPA modem chat script
#

though I use uhso(4) with Orange network, so you will need some minor
modifications to tty (for u3g) and APN (for O2)

% pppd call hsdpa

just connects it..
