hey, it's me again, with some more usb problems! :D (...or not, I don't actually know)

so i'm spending the summer abroad and I have a laptop (from early 2000 :ROFL: ) and I have a Huawei Mobile Broadband E173 USB Module with a SIM-Card in it, that I use for my internet connection, r rather would like to use.

So when I first plugged it in I clicked the network management icon (KDE4), enabled mobile broadband and set everything up in the settings (added a connection, chose country and operator and so forth) and everything worked fine. But then after 15 minutes the 1,8GHz single-core cpu couldn't withstand the almighty power of 5 google chrome tabs and everything froze, so I turned the thing off by pressing the power button for 5 seconds and rebooted. Now every time I try setting up the connection the same or any other way I get this

help :s

your changes got corrupted when you forced powering off of your system.

try this (run as root):

Code: Select all

cp -a /mnt/live/memory/images/002-xorg.xzm/etc/dbus-1/system.d/* /etc/dbus-1/system.d
cp -a /mnt/live/memory/images/002-xorg.xzm/usr/share/dbus-1/* /usr/share/dbus-1
and reboot.

if that wont help then drop your changes and configure your system from the beginning.

Thanks for the fast response!

When I try to close the window after running the commands you gave me it tells me there's a bash command running... I waited for 20 minutes it was still the same :s

you can try to use AT-commands directly.

My DLink DWM-156 will not work correct with the modem-manager.
I guess the reason is that the stick are to special:

after switching i must reload the kernel modules:

Code: Select all

modprobe -r -v option usb_wwan usbserial
modprobe -v usbserial "vendor=0x${tarvend}" "product=0x${tarprod}"
modprobe -v usb_wwan
modprobe -v option
(no idea why, and no idea which affect this have for other usbserial devices. But Im very interested)

Them i have 3 new devices:
/dev/ttyUSB0 = no funktion will not be needed ???
/dev/ttyUSB1 = Control device to send AT-Commands
/dev/ttyUSB2 = Modem device for the pppd option-file
But sometimes the are interchanged.
Very ugly!

It is possibility to detect them which device have which funktion automatic ?
It can be happend that i have a other ttyUSBX device.

After this you can use AT-commands like this.

Code: Select all

chat -t 5 -s -v ABORT ERROR ABORT BUSY ABORT 'NO CARRIER' "" 'AT+CFUN?' OK 2>&1 1>/dev/ttyUSB1 0</dev/ttyUSB1
(this command ask for the device status)
