Re: 3G dongle getting detected as USB disk on Fedora 18

[Soham Chakraborty <sohamwonderpiku4u@xxxxxxxxx>]

Alright, I learned about usb_modeswitch and usb_modeswitch_data and after hell lot of poking with libusb and friends, got some inspiration. But, then again.

[root@blah ~]# cat /etc/usb_modeswitch.d/19d2\:0154 | grep MessageContent

MessageContent="5553424312345678000000000000061e000000000000000000000000000000"

[root@blah ~]# usb_modeswitch --default-vendor 0x19d2 --default-product 0x0154 --message-content 5553424312345679000000000000061b000000020000000000000000000000

Looking for default devices ...

 No devices in default mode found. Nothing to do. Bye.

Afternoon folks,

I know that Fedora 18 is kinda obsolete but for a number of reasons, I have to stick to it for the time being. However, I am quite sure that this problem/behavior isn't restricted to F18. But since I am using that, ought to say that.

So, here is the problem.

I have a ZTE K3800 dongle which I use for wireless/3G connection, provided by Vodafone. When I plugin the device, it prompts to connect and works. Problem is, as soon as I connect, systemd sends a signal 15 to network-manager and the applet disappears from system tray. Therefore, if I try to configure VPN, I find no option. Note that, I am only trying to configure from the nm-applet. 

lsusb shows me this

  bLength                18

  bDescriptorType         1

  iProduct                2 ZTE WCDMA Technologies MSM

  iSerial                 4 MF6560ZTED010000

Now, when I insert the device, I get this.

NeedResponse=1

I checked in /lib/udev/rules.d/ to see whether I can find anything but not much success.

BTW, this article gives some clues but I don't have the configPack.tar.gz file to clone. 

http://simko.home.cern.ch/simko/usb-3g-modem.html

Any help will be appreciated. Also, if any other information is required, do shout and I will provide.

Thanks,

Soham
