["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

truant, as per
http://www.toshiba.co.uk/innovation/download_bios.jsp?service=UK an
update is available for your BIOS (6.30). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change
anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  090c:1000 file transfer to/from USB 2.0 flash drive, via 3.0 port at
  best 50-60 Mb/s

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  USB transfers to/from flash drives are very slow. Disk Utility reports
  the various drives I've tried are connected at 480Mb/s, but it's rare
  to see transfers faster than 50-60Mb/s at best, probably less as
  nautilus only reports average speed which is skewed by the first 300Mb
  being buffered.

  Sometimes I get the first 300MB very fast followed by very slow and
  ending with a long pause while the write buffer writes out, sometimes
  they're just very slow from the start. Doesn't seem to matter if I'm
  transferring one big file or lots of little files.  Seems faster with
  USB HDs.  Flash drives I've tried so far are all working fine in other
  OSes on the same machine.

  Also occurring with bleeding edge kernel (which I'm using because
  anything younger won't suspend properly on my machine),
  3.5.0-999-generic #201207280406 SMP Sat Jul 28 08:07:29 UTC 2012
  x86_64 x86_64 x86_64 GNU/Linux.

  The reason I'm reporting it here rather than at kernel.org is that I
  don't think it's a kernel bug, I think it's to do with Debian/Ubuntu's
  kernel patches.  Because it doesn't happen in the live version of
  Fedora 17 I tried, but it does happen with Debian Wheezy.  Windows 7
  is also fast.
