** Description changed:
Please bear with me as I am a n00b at Xubuntu (Xubuntu 8.10 Intrepid as
far as I can tell) running an XFCE desktop.
I have a ZTE MF637 Broadband dongle which I cannot connect to the
internet with. I see that there have been problems with the older MF622,
MF626, MF628 and MF632 but I don't see anything about the MF637. I've
been trying to get mine working using the same solutions but have come
to a dead end where i don't see what the modification for (gedit
/usr/share/hal/fdi/information/10freedesktop/10-modem.fdi) file which
was reported in bug #305968. On top of that, I tried to do the
modification for what IS in the file and I don't seem to have
permissions to do it and I don't know how to give myself those
permissions. What I am hoping is that these bugs are already resolved,
but if they are, I don't understand how they still exist since I only
downloaded and installed my Xubuntu 8.10 Intrepid about 18 days ago.
A little background on my problem: I bought the USB dongle to connect to
the internet faster than what I have now. Currently I am connecting
through a Motorola C380 and using it as a modem via USB. It is only
getting about 10kps at max so I bought this dongle hoping it would work
just as easily but unfortunately not the case. I went online to try to
see if there were any packages i could install via Synaptic Package
Manager that might help. I've installed a few which managed to make the
Dongle's light go blue (3G operational) instead of the steady red
(communication error). With this, i thought I was making some progress
but no luck after that. I've downloaded a few other packages but none
seem to help. They were "3G managing" packages for 3G dongles.
Originally I thought the issue was that my computer was not even
recognizing the dongle because when i went to Terminal and punched in
LSUSB, or DMESG, i never got any change. The other thing is that I am
using a PCMCIA to USB adapter card for my USB devices. These devices all
work fine but when I plug in the dongle, the PCMCIA card freezes up and
I lose communication from it. I have to remove the dongle and reset my
PCMCIA card and then the devices work again.
I think thats all the information I can tell. I don't know of anything
else to do.
-----------------------------
Here is a bit of an update as I have been trying to get this to work. It
turns out that part of the problem is the dongle's interface with my
Nexxtec PCMCIA card. When the dongle is plugged into it, it freezes the
card up so it does not show up on the LSUSB commanded device list.
I plugged the dongle into my replicator USB port (I am using an IBM T43
with a replicator dock) and I got a device id --- Bus 002 Device 006: ID
19d2:2000. Now checking this against my 10-modem.fdi file, this vendor
ID is correct as it comes up with ZTE or ONDA, but the device ID is
wrong as it should be 0002. I tried a couple of different things
including modifying the 10-modem.fdi file but to no avail. The computer
does not recognize the device as anything other than the "Bus 002 Device
006: ID 19d2:2000" identification.
Next, I did some research with a lot of help from another fellow Linux
user and came across USB_modeswitch. I already had the file installed
but had to change the conf file. This is the part I changed (or de-
commented):

With that done, I believe that I should have been able to enact the
usb_modeswitch to engage the Broadband part of the dongle and disengage
the ZeroCD (false pendrive) portion. Unfortunately that did not work
either so the next step was to Blacklist the usb-storage by (sudo gedit
/etc/modprobe.d/blacklist). I did that hoping that it would bring the
USB storage back to the default but that didn't work either. After
trying that and retrying the usb_modeswitch, i keep getting the
notorious (-2) error which states that the device cannot unlock or
communicate. This is the error.
sudo usb_modeswitch

Can anyone help me here? I know there is a way to get this working, I
just need to find it.
-----------------------------------------------------
Second update here....
Here is a bit more of an update on my problem. I continued on
troubleshooting and came across this set of commands in one of the
forums and tried it out. This is what I did.
sudo gedit /etc/udev/rules.d/ZTEMF622.rules
With that, I created a rules file for the ZTEMF637 even though the name
was 622, I didn't see it to matter much since the product and vendor Ids
are identical. Next, I filed in the file with...
ACTION!="add", GOTO="ZTE_End"
# Is this the ZeroCD device?
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD"
# Is this the actual modem?
SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem"
LABEL="ZTE_ZeroCD"
# This is the ZeroCD part of the card, remove
# the usb_storage kernel module so
# it does not get treated like a storage device
RUN+="/usr/src/usb_modeswitch-0.9.2/usb_modeswitch -d 1 -v 0x19d2 -p 0x2000
-V 0x19d2 -P 0x0001"
LABEL="ZTE_Modem"
# This is the Modem part of the card, let's
# load usbserial with the correct vendor
# and product ID's so we get our usb serial devices
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
# Make users belonging to the dialout group
# able to use the usb serial devices.
MODE="660", GROUP="dialout"
LABEL="ZTE_End"
And then I saved this file in the location I made it in (
etc/udev/rules.d/ZTEMF622.rules )
Next, I did this
sudo gedit /etc/wvdial.conf
[Dialer Defaults]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/ttyUSB0
Username = user
Dial Command = ATDT
Password = pass
Baud = 460800
I saved the file and closed it. Then I shut my computer down and
rebooted and tried the sudo wvdial command and I got
--> WvDial: Internet dialer version 1.60
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
Now this is where I stand now although I HAVE noticed some interesting
changes. I no longer have the same issue with my PCMCIA card interfacing
with the dongle. If I reboot the system with the dongle in the PCMCIA
card, the card functions fine AND the dongle shows up on the LSUSB
commanded device list. The only problem is if I pull the dongle out,
everything freezes up and my entire system becomes unstable which is
odd.
Also, I noticed in DMESG that the usb-storage is now ignored for this
device just as I wanted, but the same problem seems to be occurring. The
device's ZeroCD sector is being shut down, but the dongle is still
unable to unmount so it can be modeswitched as demanded in the Rules
file. This has me a bit confused as to how to overcome this issue. I
think it could be that OR that it DID modeswitch but it just can't find
this /dev/ttyUSB0 file which gives it the direction to activate the
broadband dongle for communication.
If anyone has any suggestions, please feel free to tell me.
It still never shows up in Network Manager if anyone is curious about
that part.

+ ---------------------------------------------------------------
+
+ Ok so whats the update for today. I guess that I have to create the
+ ttyUSB0 file so I did that with the :
+
+ sudo mknod /dev/ttyUSB0 c 188 0
+
+ Command. Not sure if that is right, but it made the ttyUSB0. Now,
+ instead of getting the “directory or file not found error”, I now get...
+
+ f...@fazl-laptop:~$ sudo wvdial
+
+ --> WvDial: Internet dialer version 1.60
+
+ --> Cannot open /dev/ttyUSB0: No such device
+
+ --> Cannot open /dev/ttyUSB0: No such device
+
+ --> Cannot open /dev/ttyUSB0: No such device
+
+
+ Wonderful. I've exchanged one ignorance of my device for another.
Nonetheless, this made me wonder a few things. One, I was wondering if all the
commands were linking together properly like the rules knowing the right
location of the modprobe and the mode-switch so I checked those out. Turns out
that the modprobe was not in the location that the Rules file was looking in so
I changed that to match. Next, I am not sure if this is right, but all the
information I am looking at says that product ID for the dongle in broadband
mode should be 0x0001. I checked my 10-modem.fdi file and noticed that the
0x0001 was in there and so was the 0x2000 so I took out the 2000. Its the
ZeroCD anyway and shouldn't need to be there. Then I checked the
modeswitch.conf file and it looked like I was changing the device ID to 0x0015
instead of 0x0001 so I changed that also.
+
+ I'm just trying to get things lined up but after a hard days work, my
+ brain isn't firing on all cylinders. I hit the command
+
+ Wvdialconf
+
+ just to see what happens and I got this:
+
+ f...@fazl-laptop:~$ wvdialconf
+
+ Editing `/etc/wvdial.conf'.
+
+
+ Scanning your serial ports for a modem.
+
+
+ WvModem<*1>: Cannot set information for serial port.
+
+ ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600
+ baud
+
+ ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200
+ baud
+
+ ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.
+
+ Modem Port Scan<*1>: S1 S2 S3
+
+ ttyACM0<Info>: Device or resource busy
+
+ Modem Port Scan<*1>: ACM0 USB0
+
+
+
+ Sorry, no modem was detected! Is it in use by another program?
+
+ Did you configure it properly with setserial?
+
+
+ Please read the FAQ at http://open.nit.ca/wiki/?WvDial
+
+
+ If you still have problems, send mail to <wvdial-
+ [email protected]>.
+
+
+ So I guess tomorrow is another day. I will have to continue my
troubleshooting. Hopefully I will have a clearer head to make some more headway
but I don't think I made much today. BTW, the ACM0 device source is my mobile
phone.
