Bug Description

Hi, it's my first publishing in launchpad :(

The story it's simple, if I plug my pendrive, iPod or another USB device, before ubuntu boots completely it's recognized :) but if I umount or unplug the device, and plug it again I can't mount it again, i have to restart my computer :(, the unique exeption to the rule is a usb mouse, i doesn't work if i plug it after or before ubuntu boots

when i do a # lsusb or $ lsusb the console shows nothing and i can't write a new command because lsusb stays open and i have to open a new console.

and my card reader doesn't works, i had seen some bugs here before and i think that when i removed bluez-utils it erased some usb thing that make the usb works weird, i had to remove bluez-utils because at the boot i can't boot normally because the computer hangs when it says "Starting Bluetooth Services" i had to press CTRL+ALT+F2, log in and write startx to start my session, some people at the "Starting Bluetooth Services" bug, says that the card reader must be unplugged to boot properly but i can't open my computer to unplug the card reader every time I turn on the computer :(

this is dmesg when i plugged the iPod after the boot, these lines are written when i plug the iPod
[ 277.305960] usb 1-1: new full speed USB device using uhci_hcd and address 2
[ 277.509067] usb 1-1: configuration #1 chosen from 1 choice

and the iPod starts charging and says "Don't disconnect" like when it's connected to another computer normally

I use Ubuntu Gutsy, and when i used to use Ubuntu Feisty, the iPod said "Don't disconnect" for one second and later the ipod showed it's principal menu, like when it's unplugged

sorry for my bad english, I speak spanish :)

please help me I spent so much time searching at google for ananswer :(

Disabling the bluetooth isn't a solution!

Can someone help me?

I have the exact same problem on Ubuntu Hardy Heron with all the latest updates installed. Also i had to remove the wrongly installed "Bluetooth Utilities" for my computer to start properly, just as the original poster. The problem seems to be the same.

I have troubles with all of my USB Devices when plugged in AFTER boot. The USB Digital Camera even gets recognized at first "Camera found" but not registered as a device.

Any help would be much apprechiated!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.


2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.
