I can't test it at the moment, but I have the same device and also tested at least two other (non-em28xx) devices with the xc3028 during the last weeks. With all devices, I'm often getting i2c errors like this, too. Usually only a few not affecting the device operation, but sometimes the log is full of them and I have to unplugg the device and plug it in again to make it work. So something might be wrong with the xc3028 driver... Maybe you just had bad luck when you tested this patch ?
