I am do not understand, why in CentOS 6.4 device with ID 12d1:1506 received ttyUSB , in my case in CentOS 6.5 device with same ID does not receive ttyUSB!
I try my modem in ubuntu 12.04, and it works! What is the problem?

Try

Code: Select all

/lib/udev/modem-modeswitch -v 12d1 -p 1506  -t option-zerocd -d

Also try the same with -t mobile-action-8280p

[astray]

I have some changes.
In this manual http://www.cmtsinfo.net/index.php?howto=3g have some good tips.

When I put

Code: Select all

/sbin/modprobe option
echo '12d1 1506' > /sys/bus/usb-serial/drivers/option1/new_id

then

Code: Select all

option 2-6:1.0: GSM modem (1-port) converter detected
usb 2-6: GSM modem (1-port) converter now attached to ttyUSB0
option 2-6:1.1: GSM modem (1-port) converter detected
usb 2-6: GSM modem (1-port) converter now attached to ttyUSB1
option 2-6:1.2: GSM modem (1-port) converter detected
usb 2-6: GSM modem (1-port) converter now attached to ttyUSB2

but

Code: Select all

crw-rw---- 1 root dialout 188, 4 Jul  1 11:54 /dev/ttyUSB_utps_diag
crw-rw---- 1 root dialout 188, 3 Jul  1 11:54 /dev/ttyUSB_utps_modem
crw-rw---- 1 root dialout 188, 5 Jul  1 11:54 /dev/ttyUSB_utps_pcui

So some questions appears
1. Why it do not work auto by default
2. What is the names added to ttyUSB_blablaba and how to fix they into ttyUSBx because next modem will receive that names, other ttyUSB gone out. So next other USBmodem will snatch ttyUSB from prevous.

[astray]

Try

Code: Select all

/lib/udev/modem-modeswitch -v 12d1 -p 1506  -t option-zerocd -d

Also try the same with -t mobile-action-8280p

Ooutput is

Code: Select all

[root@localhost udev]# /lib/udev/modem-modeswitch -v 0x12d1 -p 0x1506  -t option-zerocd -d
D: Found mass storage device:
D:   Endpoints: 3
D:   Class:     0xFF
D:   SubClass:  0x2
D:   Protocol:  0x1
E: no device found.

ttyUSB not appears...

IMHO something wrong with /sbin/usbmon or 40-usb_modeswitch.rules but don`t understand! Please help!

usbcore: registered new interface driver huawei_ether

huawei_ether is not a CentOS 6.5 supplied driver. Your best bet is to revert all your fiddling (if you still remember evrything) and start anew from a clean system. If you cannot get usb_modeswitch to work, you can switch your device permanently to modem mode with AT^U2DIAG=256 (->google).

To solve problem with long ttyUSB names i try to comment this strings in 10-Huawei-Datacard.rules

Code: Select all

#SUBSYSTEMS=="usb",ATTRS{modalias}=="usb:v12D1*", KERNEL=="ttyUSB*", ATTRS{bInterfaceSubClass}=="02", ATTRS{bInterfaceProtocol}=="01", NAME="ttyUSB*"
#SUBSYSTEMS=="usb",ATTRS{modalias}=="usb:v12D1*", KERNEL=="ttyUSB*", ATTRS{bInterfaceSubClass}=="02", ATTRS{bInterfaceProtocol}=="02", NAME="ttyUSB*"
#SUBSYSTEMS=="usb",ATTRS{modalias}=="usb:v12D1*", KERNEL=="ttyUSB*", ATTRS{bInterfaceSubClass}=="02", ATTRS{bInterfaceProtocol}=="03", NAME="ttyUSB*"

and now even dmseg show ttyUSB:

Code: Select all

usb 2-6: new high speed USB device number 17 using ehci_hcd
usb 2-6: New USB device found, idVendor=12d1, idProduct=1506
usb 2-6: New USB device strings: Mfr=2, Product=1, SerialNumber=0
usb 2-6: Product: HUAWEI Mobile
usb 2-6: Manufacturer: HUAWEI
usb 2-6: configuration #1 chosen from 1 choice
option 2-6:1.0: GSM modem (1-port) converter detected
usb 2-6: GSM modem (1-port) converter now attached to ttyUSB0
option 2-6:1.1: GSM modem (1-port) converter detected
usb 2-6: GSM modem (1-port) converter now attached to ttyUSB1
option 2-6:1.2: GSM modem (1-port) converter detected
usb 2-6: GSM modem (1-port) converter now attached to ttyUSB2

but ttyUSB not appears in /dev
How to return numered ttyUSB instead named ttyUSB?
I need to connect 4 usb modems and names wil be conflict together.
Please explain, why when I disable udev rule that renames device ttyUSB*, it does not appears at all?

May be my modem unsupported:

Code: Select all

[root@localhost rules.d]# modprobe -c | grep -i 12d1 | grep -i 1506
<nothing>

This output another my modem that work fine:

Code: Select all

[root@localhost rules.d]# modprobe -c | grep -i 19d2 | grep -i 0016
alias usb:v19D2p0016d*dc*dsc*dp*icFFiscFFipFF* option

How to add support of first device?

[astray]

I make udev rule but it does not work:

Code: Select all

ACTION=="add", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1506", RUN+="modprobe usbserial vendor=0x12d1 product=0x1506"

When system restarted or modem reinserted ttyUSB* not coming.

When I am put Command alone it work perfect and ttyUSB appears!

Code: Select all

modprobe usbserial vendor=0x12d1 product=0x1506

What I am do wrong? Why udev not using rule?
