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
+++ b/sys/dev/usb/serial/umodem.c
@@ -136,6 +136,7 @@ static const STRUCT_USB_HOST_ID
umodem_host_devs[] = {
{USB_VPI(USB_VENDOR_KYOCERA, USB_PRODUCT_KYOCERA_AHK3001V, 1)},

{USB_VPI(USB_VENDOR_CURITEL, USB_PRODUCT_CURITEL_PC5740, 1)},
+ {USB_VP(0x06e0, 0xf107)},
};
/*
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:
