I have no idea. Never heard of this USB device before. Apparently it requires two drivers, one for USB to serial emulation and one for the device itself, none of which is in the upstream kernel tree. The former is binary-only and is in user-space. This means you will never be able to use kernel I2C chip drivers on top of it. And anyway I would run away from binary solutions. The device in question supports the I2C transactions you need (if I trust their website) but I wouldn't recommend it for technical (software) reasons. -- Jean Delvare http://khali.linux-fr.org/wishlist.html -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
