I also managed to find /sys/devices/pci0000:00/0000:00:11.0/dwc3-device.1/gadget/net/usb0 with $ find /sys -name usb0 -prune Apparently, usb0 gets created because my system loads the g_multi gadget. But when I plug a hub into the USB port, (to which a cdc_eem device is attached), the driver configures itself as a host, enumerates my device, and sets up usb1. Poking around the kernel configuration, I see that "DWC3 Mode selection" is set to "Gadget only mode". I am guessing that "Gadget only mode" means something different than I would have expected, which is a good thing, because I'm not sure I ever would have tracked that down based on the path I was following previously. Anyway, all is well that ends well.
