Yea, I can't see why - I'd have to read the I2C specs again, but I think any device to meet the 100KHz, 400KHz specs would have to be able to sink some given amount of current for a bus length of X....

So yea, it's weird that it ended up being 100Kohms.

Anyone know how many devices are on the bus? I can only think of 2.
