Comment 17 for bug 1729674

This is a Dell XPS 13 connected to the network via the TB16 dock.
Kernel is: Linux ag13.local 4.12.0-0.rc3.git0.2.fc27.x86_64 #1 SMP Tue May 30 19:36:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Host controller of the dock:
09:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host Controller

USB network interface in the dock:
