Re: [Bug 1577898] Re: thunderbolt hotplug is broken

 

Hi Joseph,

Yes, thank you.  I just tested with a Dell USB Type-C ethernet adapter (PN#
96NP5).  In the existing latest Xenial kernel hotplug did not work.  Device
wasn't present in lsusb.
After installing that kernel i'm able to hotplug and device is present in
lsusb.

Thanks,

Bug description:
  Thunderbolt hotplug is broken on type-c ports.  Redhat already
  submitted a patch for this that was accepted into upstream ACPICA, but
  it needs to be backported into Ubuntu's kernel.

  I've verified that the patch works properly using a type-C USB
  Ethernet dongle as well as hot-plugging a Dell TB15 dock.
