ubuntu doesn't recognises usb devices plugged after boot

[Felipe Sánchez]

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 :(

I have a same problem... Computer freezes, says: "Starting Bluetooth Services"
Ubutnu 7.10
Disabling the bluetooth isn't a solution!

Can someone help me?

Thanks!

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.

--or--

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.
