Any plans for support for this or anything like this? My GA-EP45-DS4, while a wonderful board, only supports speed control on one fan which is just not enough. I was planning on building a USB to I2C bridge myself but the Tiny USB I2C looks like it might be a lot cheaper than what I was planning on using.

I bought a few OSIF USB Master devices, so that I could test and possible make up a few different I2C slave devices, but so far, I have not yet been able to make any slave devices because I have not been able to track down and purchase and I2C chips in the country (ZA) that I am in ... Currently looking overseas to see if I can ship anything in. When I have a running system, under Linux, I will send a work OSIF and I2C slave device to Alfredo Milani Comparetti, hoping that if he has a system in hand, that he might find time to add support for it.

Try requesting some samples from Maxim. I got three MAX6660's from them which should do the job just fine; you can't get them in DIP but SparkFun sells an SSOP to DIP adapter that works just fine (sku BOB-00498).
