Normaly the type is i2c. "i2cdetect -l" queries the bus functionality to find out whether it can do raw I2C or only SMBus. If it returns "dummy" this means that the functionality request itself failed (which would probably be confirmed by "i2cdetect -F"), which isn't necessarily surprising if the i2c-tiny-usb driver is crashed. -- Jean Delvare
