Edit: Here is the working config for the Option 401

###################################################### 
# iCON401 HSUPA 
# 
DefaultVendor= 0x0af0 
DefaultProduct= 0x7401 

TargetClass= 0xff 

MessageEndpoint=0x01 
MessageContent="55534243785634120100000080000601000000000000000000000000000000" 

ResponseEndpoint=0x81 
NeedResponse=1

Hi all

I've been trying to get this USB modem working on my Ubuntu 8.10 box, and I think modeswitch could fix my problem.

However my vendor model isn't listed in the conf file, so I'm not quite sure what the TargetVendor/Product should be.

lsusb lists the "Option" device, it's class is specified as a 'mass storage device'. Since I'm not sure what the Target ven/prod should be, I tried modeswitch with a TargetClass=0xff, with no success.

Here is my conf (with vendor+product as listed in lsusb):

Code: Select all

DefaultVendor=0x0af0 
DefaultProduct=0x7401 
TargetClass=0xff 
MessageEndpoint=0x05 
MessageContent="55534243123456780000000000000601000000000000000000000000000000"

with this result:

Code: Select all

sudo usb_modeswitch 

 * usb_modeswitch: tool for controlling "flip flop" mode USB devices
 * Version 0.9.5 (C) Josua Dietze 2008
 * Works with libusb 0.1.12 and probably other versions

Looking for target devices
 No target device found
Looking for default devices
 Found default devices (1)
Prepare switching, accessing latest device
Looking for active default driver to detach it
 No driver found. Device probably not initialized. Trying to continue ...
Setting up communication with device
Trying to send the message
 Sending the message returned error -2, trying to continue ...
-> See /proc/bus/usb/devices (or call lsusb) for changes. Bye

And this is where I'm stuck. I tried using SniffUsb (a version 2.0 that works in Vista, found here) but I'm not quite sure what I should be looking for in the log.

Am I just missing something important, or doing something silly? This is all pretty new to me, any tips or suggestions will be great!

Thanks in advance, wes[/code]

This device is listed in "unusual_devs.h" in kernel 2.6.28. It has an issue with a wrong device descriptor. This entry is supposed to make the storage part work.

I suspect that the failed binding of usb-storage prevents the device from accepting the switch command.

Solution? First blacklist usb-storage completely; the switching SHOULD work then. If it does, you might consider building your kernel and play around with the entry mentioned above.

There is annother source of error. If you're experimented with different settings before, be sure to always re-plug the device before trying anew. It might have gone to some undefined state.

Read my post about vodafone 3760, likely the two devices are almost the same.

Try EP 0x01 instead of 0x05

Here's the usb_modeswitch.conf that I use on my laptop running Fedora 9 Kernel-2.6.27.9-73.fc9.i686.

######################################################

Here's the output of "usb_modeswitch" with above configuration.

After the storage has been switched, you will need the HSO driver from Option (hso-1.6 and above) to get it to work. If the HSO driver is "modprobe" correctly, it will create 4 ttyHS* devices in /dev directory.

The dialup modem port that you want to use is "/dev/ttyHS3". I then use the "wvdial" to initial the connection.

Hope it helps. Good Luck

Hi Josh, thanks for the replies! I will read through your post about the 3760, and will report back after some testing - Either tonight or later this week

@hsdpafever thanks for the conf, I will definitely go over this too!

Thanks, hsdpafever, I needed this confirmation.
I'll post a new config file in the next few minutes.

Since this device is handled in "unusual_devs.h", I'd be interested to learn if the SD slot is working properly after switching.

Hi Josh,

I don't have any SD card with me, otherwise I would be very happy to test it out for you.

Confirming that the config posted by hsdpafever does work for my Option 401, thank you!

And for interestes sake, I then followed this pharscape article to get the device working on Ubuntu Intrepid Ibex.
