I have a very similar situation. However, my USB-to-I2C device came with a C library, so my code simply has to execute i2c_read() or i2c_write() functions. Then the library takes care to talk to the driver, then the USB-to-I2C device and so on. It is pointless for me to give you the code that I use because we have a custom device and custom library (made specifically for my company).

Since you have the "write" example, there should have been the read functionality as well.

Since you did not provide any particulars on which USB-to-I2C device you have, this is all the information that can be provided.
