Black, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/Kernel/MainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to 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 by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

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:
  can't change usb_charge attribute in /sys/devices/platform/sony-laptop

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am on a Sony VAIO svf43142sn. My laptop has the ability to leave a USB port powered on even after shutdown to charge other devices. The value of /sys/devices/platform/sony-laptop/usb_charge is 1, but the USB port is not powered on. Also when I tried toggling it to 0 it resets back to 1 when I check again using cat. So I restarted the module sony-laptop with debug flags on. When I try:
  echo -n 0 | sudo tee -a /sys/devices/platform/sony-laptop/usb_charge

  these are the curresponding kernel logs, implying that it was a success:
  [ 9121.879908] sony_laptop: found handle 0x0155 (offset: 0x07)
  [ 9121.881386] sony_laptop: __call_snc_method: [SN07:0x0000000000000107]
  [ 9121.881394] sony_laptop: called SN07 with 0x0107 (result: 0x0000)

  But if I cat the value of usb charge, the change is not reflected, and I see this when I dmesg:
  [ 9346.202318] sony_laptop: found handle 0x0155 (offset: 0x07)
  [ 9346.202489] sony_laptop: __call_snc_method: [SN07:0x0000000000000007]
  [ 9346.202494] sony_laptop: called SN07 with 0x0007 (result: 0x0001)

  If it matters, when i simply echo 1, I will get this:
  [ 9879.675844] sony_laptop: found handle 0x0155 (offset: 0x07)
  [ 9879.676878] sony_laptop: __call_snc_method: [SN07:0x0000000000010107]
  [ 9879.676885] sony_laptop: called SN07 with 0x10107 (result: 0x0000)

  The entire debug message when I restart the module(sony-laptop) is given here: http://paste.ubuntu.com/11551226/ . I have asked the same as a question on askubuntu.com. It has got a other information if you need it:
