[Bug 1255522] Re: [Acer Aspire 5943G] Slow copy transfer rates by bad USB 2.0 detection in external usb storage devices

 

Angel Guzman Maeso, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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-v3.13-rc1

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.

** Description changed:

- 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.
