Kevin Brubeck Unhammer, on the hardware you originally reported with
(Lenovo A740), to keep this relevant to upstream, one would want to
periodically check for, and test the latest mainline kernel (now 4.10)
as it is released.

Could you please advise?

Title:
  Copy of large files from USB3 card reader fails mid-way

Status in linux package in Ubuntu:
  Expired

Bug description:
  I've got a "Lexar Professional Workflow XR1" CF card reader that
  supports USB3, and has worked fine for regular JPG/CR2 images (sizes
  up to about 20 MB), but when I tried some videos (which were 170MB and
  up), the copy would fail around midway with "Error Splicing File:
  Input/Output Error" from Thunar, and dmesg showed messages like:

  I tried a fsck.vfat, but that didn't help. Ejecting and unmounting, I
  was able to copy one file, but not the rest (tried a couple times,
  just got the same errors).

  This computer only has USB3 ports. So I tried another computer
  (running Xubuntu 14.04) that had a non-USB3-port, and there the copy
  worked just fine.

  
  On connecting, dmesg says:
