OS3 USB bug

[Snoozer]

I'm getting lots of communication errors with the new OS. Install went fine and the OS has updated and at first it played fine but now but when I load the control the USB icon doesn't come on in the Ti display panel and it still plays the patch loaded in the hardware rather than the Control. I have tried the Control centre and it says to attach the Ti to my computer but it is attached. Firmware is def OS3 on the Ti. There is no problem with the USB connection as far as I can see - I even tried uninstalling and reinstalling the drivers and that went fine but the Control centre still reports no device is attached.
