When connecting any usb stick to my thinkpad ubuntu 10.10 does not recognize them. I don't see anything on the desktop.

the output of "dmesg | tail -n10" gives me:

[ 1965.696388] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1965.884537] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1966.072503] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1966.260349] hub 1-0:1.0: unable to enumerate USB device on port 1

[ 1966.760379] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 1966.948358] hub 1-0:1.0: unable to enumerate USB device on port 1

[ 1967.325423] hub 1-0:1.0: unable to enumerate USB device on port 1

When connecting my usb scanner to the same port:

[ 2008.480135] usb 1-1: new high speed USB device using ehci_hcd and address 65
[ 2008.548389] hub 1-0:1.0: unable to enumerate USB device on port 1

[ 2009.112348] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 2009.300443] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 2009.488536] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 2009.732180] usb 1-1: new high speed USB device using ehci_hcd and address 71
[ 2014.796299] hub 1-0:1.0: unable to enumerate USB device on port 1
[ 2018.000128] usb 2-1: new full speed USB device using uhci_hcd and address 3

And ubuntu 10.10 recognizes that scanner. So What can i do to see my usb stick? On my other Thinkpad running fedora 14 it works perfectly...

It happens only to storage media (usb sticks, cameras, etc.). My scanner (HP scanjet 2200c) works like a charm.

Don't know if any of these ideas will help you, but here I go.... Some options to check (I'd start on points 3 and 5):

  1. Check this question, too: USB Storage Device Automount, and try the solutions proposed there.
  2. Also, you can try palimpsest to check if it's detected and then mount it.
  3. In 10.04 (some people reported it with 10.10, too) there seemed to be a bug that prevented usb automounting. Don't know if that's fixed, but you can try the solution for that case (note that it disables floppy support): sudo modprobe -r floppy (source)

  4. Yet another possibility (quoting this):

    I eventually solved this problem by uninstalling pmount, then re-installing together with libpmount0.0

    Now drives are detected, automount and can be safely removed. No idea what caused the problem on the upgrade, but hope that this helps other people with the same problem.

  5. Here you can find another workaround:

    gksu gedit /etc/modules

    Add two lines (at the end of file):

    usb_storage 
usbhid

    (Actually you can check with modprobe -l |grep usbhid and modprobe -l | grep usb_storage if those moduled are already loaded or not before doing the edit.)

I've seen this a couple times lately and it always turns out to be a USB hub or port (hardware) problem. Have you tried different ports and bypassing any hubs?

Check your groups. I've had similar problems due to not being in the floppy group.

To see what groups you're in, run:

groups

If you're not in the floppy group, you can add yourself to it by running:

sudo usermod -a -G floppy $USER
