Hi Felipe,
I noticed a regression on g_audio (uac2) with dwc3 udc on v4.14:

The following patches concern ->disconnect() callbacks made when a
gadget's D+ pullup is turned off. Currently we don't have a fixed rule
for such callbacks.

The net2280 UDC driver invokes the gadget driver's ->disconnect()

issue the callback, so tha

I would go file a bug with Ubuntu and tell them to upgrade their kernel
:)
The patch was never in any 4.15 kernel releas
