[Bug 1488899] Re: USB keyboard not recognized Meizu 4

 

not really unity either... must be the USB drivers/kernel. Not sure if
the MX4 even supports this. Moving to canonical-devices-system-image for
further dispatching.

** Package changed: unity8 (Ubuntu) => canonical-devices-system-image

Title:
  USB keyboard not recognized Meizu 4

Status in Canonical System Image:
  New

Bug description:
  expected: 
  using Meizu Ubuntu phone on screen keyboard
  plug in usb keyboard
  type on keyboard
  letters appear on phone

  what happened instead:
  no letters appear, even after I restart, even after I wait for a while, even if I plug in or don't plug in the power supply to OTP cable

  I have an external keyboard and OTP cable which are recognized by my android Nexus 7. 
  I am trying to use them with my Meizu 4.

  I think I have got it to work once. I can't remember. 
  I have left the keyboard in for a while, and it doesn't work.

  OS: Ubuntu 15.04(r3)
  Last updated 6/30/15
  (no updates available)

  I am just a normal user, haven't tried to become a developer user.

  I've searched for the word keyboard in the settings. Don't see anything.
  I've searched in apps. Don't see anything helpful.

  I'm happy to debug, but not sure where to start.

  I've searched for USB in the bugs reported, and don't see it.

  I've looked through some questions:

  This is about desktop ubuntu. I don't see the  "System Settings / Universal Access / Typing" on my phone.
