Glauco, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  USB storage device slow with reset and I/O error

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: linux-source-2.6.38

  USB storage devices will start at a 20MB/s transfer and after a few
  seconds (250MB ~ 300MB), it will slow down to under 1MB/s.

  Steps to reproduce:
  Insert any USB Hard Drive or Stick to a computer running Ubuntu Natty Narwhal and start to copy a file, bigger than 500MB, from computer to USB storage device. After a few seconds at USB 2.0 speed, it will slow down to USB 1.0/1.1 speed.

  Dmesg output will report several ehci_hcd resets, followed by several
  I/O errors. After a couple of minutes, a loop with ehci_hcd resets and
  I/O error messages returns to dmesg output and the remaining data will
  be writen at less then 500KB/s, eventually aborting the process with a
  fatal error.

  Tested it a dozen times, with 2 500GB Hard Drives on 5 different USB cables and with 2 8GB USB Sticks.
  All cables are working flawlessly and all storage devices were formatted with no error or bad blocks.
