Bug Description
To connect my PC to the Internet, I firstly 'switch' my modem using the following command :
root@Evan:
L: find_device(): Found mass storage device:
L: find_device(): Endpoints: 2
L: find_device(): Class: 0x8
L: find_device(): SubClass: 0x6
L: find_device(): Protocol: 0x50
L: find_device(): Found modem mass storage device '002'
L: main(): 002: found already attached driver 'usb-storage'
L: switch_
then wvdial to finaly be connected.
In my dmesg log (sent automatically), the first command was launched at
[ 68.868184] usb 1-1: USB disconnect, address 2
followed by backtraces.
So I unplugged my Huawei E1552
[ 157.342812] usb 1-1: USB disconnect, address 3
then plugged it
[ 165.484040] usb 1-1: new high speed USB device using ehci_hcd and address 4
switched my modem
[ 262.965592] usb 1-1: USB disconnect, address 4
and launched wvdial wich enables me to report this bug
[ 291.655950] PPP BSD Compression module registered
This is a close bug of this one https:/
but dmesg log seems a bit different.
Forgive me if I duplicate a bug.

Hi Igbaäl,
This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http:// cdimage. ubuntu. com/releases/ .
If it remains an issue, could you run the following command from a Terminal (Applications- >Accessories- >Terminal) . It will automatically gather and attach updated debug information to this report.
apport-collect -p linux 447419
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
