USB_ModeSwitch

Posted: **03 Jan 2012, 00:03**

Hi,

i've got a strange behavior with my D-Link DWL-156 Revision 3.

My setting:
Netgear WNDR3700v2
OpenWRT Backfire - 10.03.1-RC6, r28680

Packages installed:

ppp - 2.4.4-16.1
ppp-mod-pppoe - 2.4.4-16.1
chat - 2.4.4-16.1
comgt - 0.32-9

The output of my lsusb:

Bus 001 Device 002: ID 07d1:a804 D-Link System

The config for the stick in /etc/usb-modeswitch.d/07d1:a804 looks like this (not changed):

CheckSuccess=20

If i run the command logread after plugging in the usb-modem I'll get the following message:

My Problem is that I neither get any /dev/ttyUSB devices nor the output of lsusb -v -d 07d1:a804 looks so good...

Can you run usb_modeswitch manually from a shell (as root)?

Code: Select all

usb_modeswitch -I -c /etc/usb_modeswitch.d/07d1:a804

The warning about "claim interface" may be harmless.

I've made a few steps in the right way - I think....

after changing the file /etc/modules.d/60-usb-serial to

Code: Select all

usbserial vendor=0x7d1 product=0x7e11
option

and installing kmod-usb-storage - 2.6.32.27-1
i'm getting rid of some "errors" in in logread/dmesg and get some ttyUSB devices

If I unplug the usb-modem and plug it in again, it doesn't seem to work so if i detach the modem I have to reboot the router (not a real problem...)

logread when i insert the usb-modem again:

Now that the ttyUSB0(1,2,3) showing up in /dev - but it looks like gcom (comgt) can't query the interface (for tests), also pppd or chat cant communicate "proper" to the modem...

I've tried to query every ttyUSB - but none of them seem to work.
PIN was disabled with my mobile-phone and the connection was established succesful with windows a few moments ago (for testing) with a windows xp test-machine.

There are several fishy things going on when I look at your data.

The device, after mode switching, has three vendor-specific (class 255) and one storage (class 8) interface.
But "usbserial" is bound to all of them, including the storage. Your "ttyUSB2" is really a confused pseudo CDROM ...
This can't be good, particularly when you try to treat it like a modem. (BTW, if talking to a interface failed, it is advised to always re-plug because the attempt may have hanged the device.)

Annother thing is that the "option" driver is available and active on your system as seen in the "lsmod" output. This driver is tailored for 3G devices and can accept new device IDs even after load time.

To solve your problems, remove the parameters for "usb-serial" that you added to "60-usb-serial". Make sure that usbstorage is available (for some devices storage initialization is essential to make the subsequent mode switch work).
Then re-plug, wait a moment until "dmesg" shows that the storage device was discovered by its driver, and start the switching process. Again, wait a moment and confirm that the storage driver has found the new storage interface.

Now issue this command:

Code: Select all

# echo "07d1 7e11" > /sys/bus/usb-serial/drivers/option1/new_id

Afterwards, "dmesg" should tell you about three serial devices provided by the "option" driver.

Finally, you should have a working ttyUSB2 which is in fact the right port for connection, but now it's actually the fourth interface.

You should be able to put all this in scripts and make it work automatically from the hotplug system. Just insert a "sleep" here and there to give the system time for adjustments.

In the original source of usb_modeswitch (designed for "full" systems), all this is automated. There were obviously space restrictions to consider for the router package version.

works like a charm...
Speed-Result: http://www.speedtest.net/result/1686774618.png - quiet OK

i've currently writing this post "via" openwrt connecting through the D-Link USB Modem.

Thank you a lot.

Next approach: creating a script that automates all the steps - which i will post here, so that the solution for this stick is complete...
After this milestone comes the bigger challenge - called ZTE MF652 (I think with a branded firmware from my provider - Hutchinson (aka drei.at)... The DWL-156 will be my 'backup-solution' because the stick don't have a antenna-jack...

Posted: **05 Jan 2012, 01:07**

The ZTE MF652 seems to pop up in several variants and USB IDs. There is one that is not yet confirmed working (never got a reply for my suggestion in this thread). But I'm confident we will get it to switch eventually.

Apart from that, "option" can take more than one new USB ID, so - once mode switching works - just use two of the "echo" commands, one for each modem, and the driver will know both of them.

Also, the connection port on ZTE devices is usually ttyUSB2, just like with your D-Link.

Saw this thread a few days ago.

Tried a few minute to apply the config mentioned in the thread.

Does'nt work for my stick - also i've got different USB-IDs...

Bus 001 Device 006: ID 19d2:1520 ONDA Communication S.p.A.

If alle the ZTE Messages won't work, I'll make a USB-Dump and post the link to it here - but further discussion in the thread...

Posted: **06 Jan 2012, 00:05**

Found a pretty simple (but I think also dirty) solution/workaround without creating a script for all the steps...

i Just added on line to the /etc/hotplug.d/usb/20-modeswitch config file:

The original file looks like:

Code: Select all

#!/bin/sh

local uVid uPid uMa uPr uSe
local sVe sMo sRe

local modeswitch="/usr/bin/usb_modeswitch"


log() {
        logger -t "usb-modeswitch" "$@"
}

sanitize() {
        sed -e 's/[[:space:]]\+$//; s/[[:space:]]\+/_/g' "$@"
}

..... and so on...

i just added sleep 3 after the logger event - and everything works just like it should...

Code: Select all

#!/bin/sh

local uVid uPid uMa uPr uSe
local sVe sMo sRe

local modeswitch="/usr/bin/usb_modeswitch"


log() {
        logger -t "usb-modeswitch" "$@"
}

sleep 3

sanitize() {
        sed -e 's/[[:space:]]\+$//; s/[[:space:]]\+/_/g' "$@"
}

and on the end of the file (after the last fi) i added:

Code: Select all

echo "07d1 7e11" > /sys/bus/usb-serial/drivers/option1/new_id

Quick and dirty - i know... but it works

Works after a reboot - so it looks good for me...

To make a "Proof of concept" i will reinstall my router this weekend and report...

Posted: **06 Jan 2012, 19:26**

Concept proofed!

Workflow with newled installed firmware (according to the manual: http://wiki.openwrt.org/doc/recipes/3gdongle)

opkg update
opkg install kmod-usb2 kmod-usb-serial-option usb-modeswitch usb-modeswitch-data kmod-usb-storage usbutils luci-proto-3g
edit /etc/config/network for your needs
edit the /etc/hotplug.d/usb/20-modeswitch and add sleep 4 like i mentioned above.

Enjoy!

PS: Strange behavoir if i unplug and replug the stick i'll getting a:
OpenWrt user.warn kernel: usb 1-1: usbfs: process 2780 (usb_modeswitch) did not claim interface 0 before use

strange...

Hi Josh. After a bit of research, I found Mageia 2 to recognize the device via usb_modeswitch 1.2.1. Three ttyUSB devices are created as expected, and strangely I can talk to modem via ttyUSB1 and ttyUSB2 devices at same time (unsolicited network status reports are dumped to ttyUSB1 only).

When I issue a 'ATD*99#' command on either serial port, device answers with a 'CONNECT 7200000' then gives no answer anymore on this port (no PPP traffic nor AT console). I can use another instance of minicom to talk to modem by the other port. Issuing 'atd*99#' after this gives a 'ERROR' response. Maybe device is already connected by another serial port?

Appears to be module option is hanging when CD signal goes up, or online data is being redirected to another endpoint. Can you give me some steps to debug?

My device is the DWL-156 3.01LA, same USB device ID.

Does your device really have the same interface setup as the other one from the post above? (Try "lsusb -v" ...)

If so, it looks like the very last ttyUSB is the one for connection. If all goes well it should be ttyUSB2 (out of three).

I will start another thread so we can investigate it. This tread is not directly related and is going too long..
