It would be nice to support named devices for USB-I2C adapters such as tiny-i2c-usb because their bus number will not be consistent between restarts. However, we can create symlinks using udev. Currently, I just symlink to /dev/i2c-my-bus1 and use "my-bus1" as bus id in smbus2. Works as a hack but it is probably not intended this way.

Further smbus extensions (#39)
e557018 
* SMBus.__init__(), SMBus.open(): `bus` can be a file path as well (issue #17).
* Whole class i2c_msg_iter replaced by a simple generator function which has the same functionality
* Added enter/exit handler to `SMBus` class.
* Added i2c_write and i2c_read, some very basic and most simple read/write operations.
* Additional test cases

Above mentioned PR lets you provide the full path, i.e. you can choose between bus number (int) and a string containing a full path.
