It was suggested that I open a bug report for this RRD issue:

I can report that my Huawei E1762 USB modem seems to work quite well on 2.0-BETA5 at least. And the PPP setup for my ISP (Australia - Internode) worked perfectly.
The only issue I have found is the RRD Graphs - Cellular does not work.

I'm not sure if RRD graphs work for the other listed Huawei modems, but the command used by /var/db/rrd/updaterrd.sh `3gstat -sv -d /dev/ugen0.2` (I added the -v) returns:

"open /dev/usb/0.2.4
writing 5 bytes
reading 75 bytes

3gstat: error reading from device: No such file or directory"

Maybe it's because the modem is available at /dev/cuaU0.0 and /dev/cuaU0.1 and not /dev/ugen0.2 not realy sure what ugen0.2 is but it is derived from the command:
dev=`usbconfig show_ifdrv | awk -F. '/ u3g|umodem/ {print "/dev/" $1 "." $2}'` which returns "/dev/ugen0.2" that is found in /var/db/rrd/updaterrd.sh

I had a look at 3gstat.c but I didn't really understand what it was doing (I'm not a programmer). However searching the net it would appear that the way to query this modem was via an AT command while connected to the device on either /dev/cuaU0.0 or /dev/cuaU0.1. For instance I can, while a PPP session is active on /dev/cuaU0.0 run `cu -l /dev/cuaU0.1` and connect to the modem then type "AT+CSQ" and get a response like "+CSQ: 11,99". See table below.

So I'm curious to know what 3gstat tries to do and why the updaterrd.sh script wants to do it on /dev/ugen0.2 and not one of the modems devices /dev/cuaU0.0 or /dev/cuaU0.1.
BTW
`3gstat -sv -d /dev/cuaU0.1` doesn't work either, returns "3gstat: getdevname error: No such file or directory"
