network-manager applet fails to detect usb devices after update to Maverick

[Ashok KP]

Binary package hint: network-manager

Currently using Ubuntu 10.10 which was upgraded from 10.04 online.

Package having problem : network-manager 0.8.1+git.20100810t184654.ab580f4-0ubuntu2

Description:
When I was using Lucid, network manager applet automatically detected any usb modem devices and made it ready for connection. After upgrade to Maverick, sometimes the devices are not at all detected. Some times after a restart, when I plug the usb and wait for around five minutes, it gets detected. There are no problems in connecting.

I tried using many devices. One Nokia E51, one Huawei EC1262 modem etc. All resulted the same.
this is what i got using lsusb for my Nokia E51.

Another thing I noticed is, its a bit complicated,
When i turn on my computer with the device already connected, then the network-manager never detects the device even after I take it back and plug it again.
And, when I turn computer on without the device and then I connect the device, then it takes somewhat 2 minutes to detect it.
But wireless networks are detected instantly under all conditions.

Hi, thanks for reporting this bug and helping to make Ubuntu better.

Could you please add some more information to this bug report? If you could include the USB ID of your USB modem, that would be great. You can get this with the 'lsusb' command. Thanks!

Ok, I have added more details.

Hmm, are you only seeing delay? It's a known issue (same happens on my USB 3G modem). Not saying it shouldn't be fixed, but let's clarify that it's mostly just that ;)

Ashok, can you confirm what I added in the previous comment?

Thanks in advance.
