In drivers/usb/core/usb.c the routine usb_alloc_dev() will
set the devpath for the root hub to "/".
Then usb_find_drivers() constructs a filename used by driverfs
using
sprintf (&interface->dev.bus_id[0], "%s-%s:%d",
dev->bus->bus_name, dev->devpath,
interface->altsetting->bInterfaceNumber);
This leads to filenames like "00:07.2-/:0" with embedded '/'.
