Does not install in Linux

8:44 AM 12/7/01

This document is designed to help install the MT5634ZBA-USB in Linux. You must have the most recent kernel, 2.4.2 or higher. You will also need specific modules for installation, they are explained below. The MT5634ZBA-USB has been tested successfully in Mandrake 8.1 and RedHat 7.2.

Please read the whole document, as some steps depend on how the Linux system was built.

You need to select the USB Modem (CDC ACM) support kernel option. If you build as modules, you need to install the acm.o option. You need to set up the device node entries for the various modems. The driver is supposed to suppport 32 modems, but only one modem was used for testing. Use the following commands to set up the first four modems:

mknod /dev/usb/ttyACM0 c 166 0
mknod /dev/usb/ttyACM1 c 166 1
mknod /dev/usb/ttyACM2 c 166 2
mknod /dev/usb/ttyACM3 c 166 3

You should now be able to use a terminal emulator program to attach to this device and connect to your modem or other terminal device.

If your current version of Linux has the ACM driver compiled into it, then you're ready to roll. If it has the driver built as a module, then you'll have to enable the driver with the following command:

modprobe acm

At this point, you may have to unplug the modem's USB cable and then plug it back in (this isn't necessary if you're using kernel 2.4.X). You should see the modem's lights come on. If you see some activity lights on the modem, type the following:

lsmod

This command will display a list of loaded modules. The ACM module should be displayed as loaded.

Now that you've got the driver loaded, you need to set up the device node (in /dev) for the modem. You can use up to 32 modems with this driver, but most people will only need to configure one. To set up a modem, use the following command:

mknod /dev/usb/ttyACM0 c 166 0

You should now be able to use a terminal emulator program to attach to this device and connect to your modem or other terminal device. Going one step further, you can set up a symbolic link from /dev/modem to the ACM modem device. This is accomplished by using the following command:

ln -s /dev/usb/ttyACM0 /dev/modem

That way, KPPP and related applications can all refer to the modem as /dev/modem without caring what type of modem it is.
