Hello,

A friend gave me a usb modem recently.  The model is:
Multi-Tech Systems - Multi-Modem USB - MT5634ZBA

The Linux driver info is here:
ftp://ftp.multitech.com/usb/usb-linux2.txt

When I plug this device into FreeBSD I get a ugen0 device.

So I tried hacking into the driver itself:

diff --git a/sys/dev/usb/serial/umodem.c b/sys/dev/usb/serial/umodem.c
index c1e8812..9886294 100644
--- a/sys/dev/usb/serial/umodem.c

  };

Now I get the following:

I read the Linux driver and it seems pretty similar, although it does
look like they have a ton more quirks and edge cases the handle.  The
file in Linux I'm looking at is: linux/drivers/usb/class/cdc-acm.c (this
seems to make the most sense given the instructions given at
ftp://ftp.multitech.com/usb/usb-linux2.txt).

I tried turning on sysctl hw.usb.debug=10 however after doing so it
didn't seem to want to probe anymore.

Any ideas?

I can ship this modem to someone if they are interested and have a good
idea how to fix.

Hi,

Can you send the configuration descriptor dump:

usbconfig -d X.Y dump_device_desc dump_curr_config_desc

Maybe the modem fits into the U3G driver.

--HPS

Hans,

Moving it to u3g on -current gives nearly same error:

Output from usbconfig is as follows:
