[ehung]

Some questions about HUAWEI E220!!! Please help me!!

Hi Tazz_Tux ..
I bought a HUAWEI E220 3.5G modem and I tried to make it work in the Fedora Core 6. The kernel is 2.6.18-1. I follow some instruction to make it work.

1. First, I insert the HUAWEI E220 into my USB and umount HUAWEI E220 device .

2. rmmod usb-storage

3. modprobe usbserial vendor=0x12d1 product=0x1003

4. remove HUAWEI E220 module and re-insert it wait a few seconds.

5. ls -la /dev/ttyU*
crw-rw---- 1 root uucp 188, 0 3月 15 17:49 /dev/ttyUSB0

6. dmesg
.......
usb 2-2: new full speed USB device using ohci_hcd and address 4
usb 2-2: configuration #1 chosen from 1 choice
usbserial_generic 2-2:1.0: generic converter detected
usb 2-2: generic converter now attached to ttyUSB0
Initializing USB Mass Storage driver...
usbcore: registered new driver usb-storage
USB Mass Storage support registered.

7. wvdial.conf

Username = username
Password = password
Stupid Mode = 1
Dial Command = ATDT
[Dialer huawei_e220]
Modem = /dev/ttyUSB0
Baud = 460800
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem

8. wvdial huawei_e220
--> WvDial: Internet dialer version 1.54.0
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.

I have no ideal what's wrong with it.
Could you give some suggestion about that,please ?
Thank you very much.

I have a similar problem:
uname -a says:
Linux puppypc 2.6.18.1 #1 Sat Nov 11 07:52:06 PUP 2006 i686 unknown unknown GNU/Linux
(Puppy-Linux; especially for embedded pcs with low cpu/ram)

using rmmod usb-storage and modprobe usbserial [...], I come to a point where the modem is detected:

Mar 15 13:49:30 (none) user.info kernel: usb 1-2: new full speed USB device using uhci_hcd and address 12
Mar 15 13:49:31 (none) user.info kernel: usb 1-2: configuration #1 chosen from 1 choice
Mar 15 13:49:31 (none) user.info kernel: usbserial_generic 1-2:1.0: generic converter detected
Mar 15 13:49:31 (none) user.info kernel: usb 1-2: generic converter now attached to ttyUSB0

(ttyUSB0 on this system seems to be /dev/usb/ttyUSB. So I changed the entry in wvdial.conf)

sh-3.00# wvdial huewai_e220
--> WvDial: Internet dialer version 1.42
--> Initializing modem.
--> Sending: ATZ
--> Modem not responding.
--> Initializing modem.
--> Sending: ATZ
--> Modem not responding.
--> Initializing modem.
--> Sending: ATZ
--> Modem not responding.

Sometimes, especially after rebooting, the wvdial states something like this:

sh-3.00# wvdial huewai_e220 
--> WvDial: Internet dialer version 1.42
--> Initializing modem.
--> Sending: ATZ
--> Modem not responding.
--> Cannot open /dev/usb/ttyUSB0: No such device
--> Cannot open /dev/usb/ttyUSB0: No such device

and at the same time, the modem seems to disconnect by itself, and is re-detected 10 seconds later:
(cannot paste log, since at the moment, it just won't disconnect. but in dmesg it looks kind of like I removed it from the USB port)

any suggestions?

Hey ehung,

I'm using Fedora Core 6 as well.. exact same kernel.. so I can confirm that the E220 does work...

I noticed that I did not need to do the unplug / replug routine...

Here's how I do it..

Insert the device then and wait till till FC automatically mounts it..
"Eject" (i.e., unmount) the device.
/sbin/rmmod usb_storage
/sbin/modprobe usbserial vendor=0x12d1 product=0x1003

At this point the system output reads:

usbserial_generic 4-2:1.0: generic converter detected
usb 4-2: generic converter now attached to ttyUSB0
usbserial_generic 4-2:1.1: generic converter detected
usb 4-2: generic converter now attached to ttyUSB1
usbserial_generic 4-2:1.2: generic converter detected
usb 4-2: generic converter now attached to ttyUSB2

And then it works... I did not have to do anything else.. so theroretically this should work for you too (same kernel, same config) but well.. sometimes it just doesn't..

Maybe I'm just lucky..

dear ehung (and all others, where the device is only detected as ttyUSB0 and NOT as ttyUSB1 and ttyUSB2)

connect the modem, and reboot (=have the modem connected while booting and NEVER remove it during that session )

do the "rmmod usb-storage" and "modprobe usbserial vendor=0x12d1 product=0x1003"

look at dmesg - maybe it is now ttyUSB0-ttyUSB2 !!!
now, maybe you have to "touch /etc/ppp/peers/wvdial" (if it doesn't exist)
then, "wvdial huewai_e220" (or "wvdial pin huewai_e220, depending on pin requirement)
