Thank you Christopher for your feedback.

I've read the instructions, they are clear and I'm convinced that
following them exactly indeed makes things more efficient for everyone.
Also thank your for having edited this bug title and first sentence they
look more in the spirit of the instructions.

For added confidence, I'm considering first testing the device on
another computer that also has USB3 and USB2 ports and/or another
distribution using a live media, then updating here then doing the
upstream report.

Regards.

Title:
  0b95:1790 [Asus N55SF] Bad performance of Ethernet-to-USB device on
  USB3 port, dmesg flooded with errors

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Plugging USB-to-ethernet device ID 0b95:1790 ASIX Electronics Corp. in
  USB3 port yields slow performance, dmesg flooded with errors. Plugging
  on USB2 port, exact same situation otherwise, works well. This is
  reproducible 3 out of 4 attempts. Machine has 2 USB3 ports on the
  left, 2 USB2 ports on the right.

  ### When working (USB2 port)
  * ethernet auto-negociation is fast
  * mii-tool is fast (typical 0.05s)
  * few lines in dmesg
  * good performance

  ### When failing :
  * ethernet auto-negociation fails, then sometimes eventually works
  * mii-tool is slow (10s of seconds instead of 0.05s)

  time sudo mii-tool
  eth0: no link
  eth1: 10 Mbit, half duplex, no link
  real	0m40.014s
  user	0m0.013s
  sys	0m0.006s

  time sudo mii-tool
  eth0: no link
  eth1: 10 Mbit, half duplex, no link
  real	0m50.015s
  user	0m0.011s
  sys	0m0.011s

  time sudo mii-tool
  eth0: no link
  eth1: negotiated 100baseTx-FD, link ok
  real	0m10.051s
  user	0m0.000s
  sys	0m0.012s

  But on some attempts mii-tool is fast...
  time sudo mii-tool
  eth0: no link
  eth1: negotiated 100baseTx-FD, link ok
  real	0m0.057s
  user	0m0.011s
  sys	0m0.012s

  * DHCP eventually completes (after about 30 seconds) then ethernet works.
  * whole system behaviour feels a little sluggish (not very clear, though)
  * mii-tool still slow (10s of seconds instead of 0.05s)

  ## dmesg when failing

  Full dmesg attached.

  Specific lines with occurrence count at random point (obtained with
  "dmesg | sed 's/^................//' | sort | uniq -c | sort -n" ).
