Public bug reported:

By recommendation of Christopher M. Penalver (penalvch), I fill this bug
in reference to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/177235

Extracted issue from comments of #177235:
"""Confirmed issue with slow transfer rates (<1.5 MB/s) for 3 different external USB 2.0 hardisk (toshiba 1 TB, SAMSUNG 512 GB, Hitachi 1 TB) with 3.12.0-4-generic from trusty. It is mainly a bad detection as USB 1.0 instead of USB 2.0 in dmesg (check_highspeed is indeed bogus). I try to test with kernel mainline v3.13-rc1-trusty but I cannot because I am affected by the bug https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1254424 in fglrx.

Copy 20 GB takes days, instead of hours for this issue. Thats
unacceptable for backups in a company or the medium user with multimedia
files. Please Ubuntu or Linux Team, contact with upstream, assign devs
and raise with more priority with this bug. Perfomance is a must in
GNU/Linux."""

This report was filled using "ubuntu-bug linux" command. The issue is
mainly to copy or move files to a USB external storage device from the
laptop or desktop. There are plenty similar reports about this issue,
but I filled this for recommentation and because the devs can obtain
some debug information about the devices.
