The snd-usb-audio driver gets these names from the device descriptors (iManufacturer/iProduct). Some devices do not have these, so the entries in quirks-table.h can override them. There are no devices that specify port names (AFAIK), so the driver has a hardcoded list for some devices in the port_info array in midi.c, and uses 1/2/... for the rest.
