adu-520a modem doing a whole lot of nothing.

[Guest]

So! I've been studying up on linux and kubuntu and would be ready to make the switch but for one thing-- my modem does not work with kubuntu 9.10, Karmic Koala. There seems to be not a whole lot of guidance as to what to do in English or in Georgian (Georgia, the country, being where the modem hails from and where I work). I'm very new to code (read: never done it before, so a little cautious), and I can't read Russian, which might help with the decoding of this: http://www.opennet.ru/base/modem/skylink_linux.txt.html.

I had a Wubi installation for a while. I tried to configure the setup of the modem as a device, and when multiple failures ensued, I uninstalled Kubuntu in a fit of frustration. Oops.

Anyway, I believe it has something to do with the USB modeswitch on the device; like, I need to halt the modem from being recognized as a storage device because that only helps Windows to recognize and auto-install whatever it needs.

Would something like this be my most likely solution?

Or, would it be best to install 9.04, which reportedly has no problems?

I'd like to get some advice from knowledgeable people who know what they're doing before I waste more hours of my life downloading a 700MB file that won't work for me because I don't know what I'm doing.

Subject: Tuning the work Of skylink EVDO with the aid of the modem Of anyData ADU-520A into Linux

Brief instruction for those, who will want to use equipment CMDA of 1x/EVDO into Linux.

It tuned for AnyData ADU-520A - but must work, also, for others
the models Of anyData.


For the tuning they will be necessary by us:

1) Any Of linux [distributiv] with the sufficiently fresh kernel, with the modules of ppp and libusb.

2) The program of usb_modeswitch, which switches EVDO- modem from the regime
Cd -ROM/MMC-Flash into the regime of modem - is taken from the WEB- site:
http://www.draisberghof.de/usb_modeswitch/

3) Pair of the scripts, one of which, using that point out above program,
we switch modem. The second script - establishes ppp connection
by provider.

Let us begin:

We download from the site the files: usb_modeswitch-0.9.4.tar .bz2 and usb_modeswitch.conf.
We unpack the first file:

tar - xf usb_modeswitch-0.9.4.tar .bz2


We cd into the directory of usb_modeswitch

We run the script:

./compile.sh


after the compile is done we copy the binary to:

cp usb_modeswitch /usr/bin/


The configuration file we copy into /etc:

cp usb_modeswitch /etc/


In our home directory we make 2 scripts: change_modes.sh and evdo-skylink.sh:

touch change_modes.sh evdo-skylink.sh.


We change their permissions:

chmod 777 change_modes.sh evdo-skylink.sh


Contents of the first file:

#! /bin/bash
/usr/bin/usb_modeswitch - v of 05c6 - p 1000 - V 16d5 - P 6502 - m of 0x00000008 \

Contents of the second file:

All, we are practically ready - it remained to neglect:

We connect modem, after 5-10 seconds we execute a command of dmesg, in order to
to look, as nucleus it reacted to the modem:

usb 6-1: new of full of speed USB of device of using of uhci_hcd and address 2

sr: Sense Of key: 0x0 [of current]
sr: ASC=0x0 Of aSCQ=0x0


Is it evident that the device did recognize as CD -ROm and all?
In the catalog /dev/ the new device appeared: /dev/sr0. Also, if in your Linux
are disposed HAL/UDEV - to you will be proposed to [podmontirovat] new
device - we reject.

We carry out script change_modes.sh, we look, that it wrote to us. If everything
successfully, after 5-10 seconds again of dmesg:

usb 6-1: USB of disconnect, address 2

Aha!!! - appeared the devices of ttyUSB0 and so forth - they that to us and they were necessary!

We start in the console script evdo-skylink.sh - connection is must to be established, through
the command of ifconfig you will be able to see the new net the device of ppp0.

Everything - the Internet will work on this of the type.

PS: If connection will be not stable, I recommend to decrease the value
the maximum speed (in my script: 921600, but with this value
real speed was: 368 kbit/s, and there were small delays, as if
modem thought).

PSS: If you have common telephone and with its connection in the catalog /dev/
immediately appears device /dev/ttyUSB0 - tambourines with the mode switch
modem are not necessary - you immediately start script - to them (at a rate of 230400) I
already 2 years I use in any [linukse] (tube Of curitel-510 + OF USB-TO-COM
pl2303 (prolific)).

I hope that my small instruction will help someone
