Hello Joseph,

## Mainline kernel: tested from Saucy, inconclusive so far

I tested mainline 3.15.0-031500rc5-generic for about 2 days.

On that kernel, the machine ran hot due to nVidia optimus chip not
turned off by bumblebee.

The problem did not appear, but it does not prove that it's fixed as it
does not happen every time.

Two times the machine got stuck. Did not react to keyboard or mouse activity. Mouse pointer visible but still. AltGr-SysRq+S did flash the hard drive led, proving that the kernel was no crashed or panic. I rebooted with the REISUB sequence.
Two semi-hangs in two days with mainline kernel is clearly different from normal kernel where this just does not happen.

## Upgraded to Trusty, problem reproduced with standard kernel

I just installed Trusty two days ago and experienced the problem again
the next day. Now running 3.13.0-24-generic.

It looks like Trusty can turn off nVidia chip without installing
bumblebee because laptop did not turn hot.

## Next step offered: run mainline kernel on Trusty

So I'm considering to run mainline kernel on Trusty as it will be
easier.

Comments welcome.

Title:
  [Asus N55SF] All USB ports gradually fail on Ubuntu, rebooting
  relieves for days or hours, booting Windows once fixes for weeks.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On my Asus n55sf laptop running 64-bit Ubuntu, USB ports gradually fail more and more until none of them works, progress can take weeks.
  Rebooting provides partial relief (but symptoms come quicker, e.g. within days then within hours. Observed with all sort of devices. Not device dependent or trigger by any specific device. actually affects USB3 ports first, then extend to USB2 ports. Machine has 2 USB3 ports on the left, 2 USB2 ports on the right. The laptop also has Windows 7 64-bit which is rarely used (say, 20 days in 2 years). All USB ports always work on Windows, no disconnect, no glitch, USB2 as well as USB3 ports fully work.

  WORKAROUND: Booting Windows for a minute solves (no problem for
  weeks).
