I have found another setting that in my case was the real cause of the problem, namely ASPM (Active State Power Management).  I had noticed that I was getting the disabled endpoint error message at odd times, like in the middle of the night, when there was little or no activity to the USB 3 disks attached to the controller.  It always struck me as odd that the problem would occur randomly like that and not be clustered around the periods of high activity.  
 
It turns out that ASPM was active by default in the BIOS, buried in a power management setting for PCI devices (i.e. it didn't say ASPM in the setting title).  Once I turned that setting off all the errors stopped, both when the devices were active and when they were idle.  I'm sort of assuming that the issues happens when ASPM tries to turn off or go to a lower power state on the USB controller.  I don't know if  this is a bug in the BIOS, firmware of the USB controller, or the linux kernel device driver, or a combination of those.   Whichever it is though, turning this off in the BIOS solved everything in every kernel version that I've tested.  I also installed Arch Linux so that I could try a recent kernel version and it works find there too.   So if you are having this problem and it the other solutions haven't worked for you, look for this setting in your BIOS.  It might be in the power management section, but also might be in the peripherals, devices, or advanced PCI settings area.

Bug description:
  based on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358871/comments/7 I tested with the HDD enclosure IcyBox IB-351 series with USB 3.0 connection with the same result (connection drops after 300 MB reading, error message "xHCI xhci_drop_endpoint called with disabled ep" occurs sometimes, other devices (e.g. Samsung HD103SI 1 TB HDD connected with 3.0 USB adapter to eSATA of enclosure) read hundreds of GB before failing, but definitely do before reading 1TB). Reading tested with `dd`, `gpart` and `btrfsck`.
  Also confirmed on Lenovo IdeaPad-Z500 after BIOS update to 71CN51WW(V1.21) (changelog didn't indicate any USB issues anyway). Also confirmed with 3.16.3 and 3.16.0-14 on Ubuntu 14.10-beta1 after updates.
  The issue seems to cause failure of ASIX AX179 gigabit ethernet chip as well, but is independent from the usage of the ethernet adapter.
  I'm without any clue and stuck with an unreliable USB and ethernet connection which basically means no I/O out of the machine!!
