I knew of the OpenSource project i2c-tiny-usb. But sadly the hardware ist not sold anywhere (At least I didn't find vendors).
As regarding to cheap serial line based adapters, there are two I have seen before [...]
None of them seems to have kernel drivers available. So I could stick to my own homebrewn Arduino solution.
I am afraid handling serial devices within a i2c kernel driver might be tricky and purists probably dislike the idea.
Currently there is at least one driver for such a case already in the kernel: drivers/i2c/busses/i2c-taos-evm.c
I found it by "grep serio.h" in i2c/busses/. But this driver rather only supports SMBus which is kind of subset of I2C. Or you could call it I2C with more strict requirements upon timing and protocol.
In fact this would have been the driver I would have based my work on if someone said: Go on, this is a good thing to include in the kernel.
But for now I think I will just publish the Arduino sketch and a sample implementation on how to access I2C devices with it.
