has anyone made this WIMAX modem work in openSUSE 11.4

Thanks

If your device shows 198f:0220 then it is already switched. No need to do anything manually.

The problem is that this device has no serial ports like the other 3G modems.* It would probably need a special driver.* Unfortunately, there is nothing I can do about that. Maybe you can ask the manufacturer …

…googling on the ID of the device gives no effective help;

…sometimes wvdial works; are you up to setting up wvdial?

If you want help, you need to tell us who your provider is

here is a further thread from usb_modeswitch for you to follow;

USB_ModeSwitch ~ View topic - Beceem BCSM250 Mobile WiMAX modem 198f:bccd -> 198f:0220

Josh suggested issuing the commands

modprobe -v option

echo “1199 0301” > /sys/bus/usb-serial/drivers/option1/new_id

where the # means superuser (su)

if you do that, and copy and paste

dmesg | grep tty
into a terminal, hopefully you will see ttyUSB0 so that should allow dialling

then

su-
to get root powers

then

gedit etc/wvdial.conf

and the suggested config file was

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Carrier Check = no
Stupid Mode = yes
Phone = #777
Username = ’ ’
Password = ’ ’

Josh suggested

You don’t need all that “Init2” stuff, abridge it to “ATE1”. Set “Baud” to “115200”.

Add a line “Stupid Mode = 1” which prevents probing.

does this give you some stuff to chew on?

Issue is: no linux driver

http://cateee.net/lkddb/web-lkddb/BCM_WIMAX.html

so need to build kernel;

advice here

http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=327&start=15&sid=bcacad7e2dc06721d3a4c4be132f26b4

some helpful others may care to jump in; read and give advice if you wish to pursue this;

likely in a few months this device will be supported; just not now

that’s right the device is in the right mode already, It was switched automatically.

the problem is the driver, so I will have to wait until the driver is created to use the device in openSUSE

5

I will have to wait until the driver is created

…well…

Linux Kernel Driver DataBase: CONFIG_BCM_WIMAX: Beceem BCS200/BCS220-3 and BCSM250 wimax support

seems there is already an experimental driver…one needs to build the module…
