Description Bartosz 2009-06-05 11:18:23 UTC

I have motherboard Asus A8V-VM and Huawei E220 USB modem.

I use both Ubuntu 9.04 Jaunty and WIndows XP.

When I run Windows XP and establish connection (Polish operator PLAY),
and next I restart Windows XP system and run Ubuntu 9.04 Jaunty, the Huawei E220 modem can't connect to the network.

Only when I turn off computer, and run Ubuntu again or I switch the USB connection, then it starts working.

The Windows XP alway connect properly to the network.

Comment 6 Greg Kroah-Hartman 2009-06-10 22:20:25 UTC

Can you try the 2.6.30 kernel release?

I don't see the hardware doing anything strange here, what shows that there is an error?

Comment 7 Bartosz 2009-06-11 18:24:09 UTC

I haven't tried 2.6.30 kernel release.

I think, that there is same information remaining at USB device during Windows XP session, which disapear when I manually turn off computer.

When I do soft restart (I do not switch off power supply), the Huawei E220 can't estabilish connection.

I think some informations is not cleared on USB device, during system start.

Could you please tell me which logs, you need to triage this bug?
Which driver, this modem use?

This error I can always reproduce.

If this is still seen on a modern kernel please re-open and update the kernel version
