What about installing different USB PORT drivers. Not usb steinberg drives for the device but strictly drivers for you USB PORT in your computer. Tried it?
yeah, i tried update and reinstall usb drivers as well. Asmedia driver for mobo bridge cotroller, and amd driver under the CPU controller
the problem occurs again, nothing has changed since last post. i see that Yamaha Steinberg USB Driver V2.1.6 hits live. will see if that helps whatsoever
