  Nec/Renasas 27xxx2 May also need Quirk in 17.04, no problem in 16.04?

Status in linux package in Ubuntu:

Bug description:
  In trying to build a zoneminder server, I think I stumbled on a kernel
  bug. It  seems to have snuck in sometime between 16.04 desktop
  promoted to server, and 17.04 server promoted to desktop.

  The suggestion is that the very popular Nec/Renasas 27xxx2 may need
  "quirk" in the kernel.


  (Scene 1)

  Loaded 16.04 Ubuntu Desktop
  Promoted Desktop to Studio
  Promoted Desktop to Server
  Added Zoneminder
  Needed more cams, added Startech  PEXUSB3S44V NEC/Renesasa 27XXX2 based card 
for more USB channels.
  Everything worked quite well. Some errors in ZM but no DMESG as far as I 

  (Scene 2)
  Wiped the drive. 
  Loaded 17.04 Server
  Now getting messages in DMESG complaining of thousands of errors:
  [96415.044917] handle_tx_event: 516 callbacks suppressed
  [96415.044924] xhci_hcd 0000:0c:00.0: WARN Successful completion on short TX: 

  Messages suggest "quirk" is the solution.
  a)Researched usb 3.0 "quirk'
  b)Noticed it's really a "thing" 
  c)Couldn't find recipe for patching kernel for NEC/Renases "quirk" fix. 

  (Scene 3)
  Anecdotes suggest Nec/Renasas firmware is to blame.
  a) Kernel indicates 2024 firmaware
  b) Startech website has 2026 firmware. 
  c) VERY IMPORTANT! WindowCentric GUI instructions do not translate between 
ASCII and HEX. So if your Startech is on channels 9, 10, 11, and 12 from 
perspective of Windows, you must translate into 09, 0A, 0B, and 0C when editing 
runfile for effective firmware update of all 4 controllers. Yes, for the 4 
channel controller, count them: 4. 
  d) Firmware updated. 

  (Scene 4) 
  Rebooted with new Startech/Nec/Renases 2026 firmware. 

  (Scene 5)
  I give up. 

  It may well be worth noting that there are no errors from DMESG until some 
seconds after the first webcam is attached to the Startech.
  And I can't overemphasize the fact that I don't think I had any DMESG errors 
under Desktop 16.04 

  I think the file attached represents DMESG immediately before the
  errors start going nuts. My theory is that ZM does lazy polls on
  missing cams but once it gets 'hold if the cam and sucking data the
  quirk bug surfaces.
