My friend having the Tyros now for 4 weeks has recently loaded the USB Driver provided and connected the Tyros to his PC. He is now getting occasional PC lock-up. We have no proof that the Tyros is causing this and there are many factors that can cause this type of fault, but it is only since making the Tyros - USB connection that the problem arisen.

Has any other Tyros owner with it connected via the USB found a problem?.
