if your modem is not supported out of the box, go to the file usbdevs and add an entry for it:

I got last week a modem not supported by FreeBSD and just did this:

product HUAWEI ETS2055		0x1803	CDMA modem

0x1803 is the ID of my modem. The ID is unknown to FreeBSD 8.2.

Then add a line like the following to u3g.c:


Check the file for the other options like U3GINIT_HUAWEI you have.

The chances are then pretty high that all will work

The next problem will then your ppp.conf.
