The kernel has to have "USB Modem (CDC ACM) support"
What is the output for "lsmod|grep acm" ?
For me it is
cdc_acm                12672  0
usbcore               113344  5 cdc_acm,usbhid,ehci_hcd,uhci_hcd
USB modems are used with /dev/ttyACM* devices
So, once the correct modules are loaded (manually or otherwise) and
the modem is "on" (for my palm treo 680, there is a "USB modem"
application I run on the handset before I do the wvdialconf step)

"wvdialconf wvdial.conf" should show something like this
Scanning your serial ports for a modem.

Found an USB modem on /dev/ttyACM0.
Modem configuration written to wvdial.conf
ttyACM0<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

The wfdial.conf reads

[Dialer Defaults]
Modem = /dev/ttyACM0
Baud = 460800
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = USB Modem
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>
At this stage, one is ready to go.
I hope there are sufficient hints here to get you started.
