Yes it is... 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.

Thanks for the tip.
