Hi! Just bought the CODE 25 amp and I've put the firmware up to date, everything seems to be ok but when I unplug the USB, the LCD reads "CHK USB". I turn it off then on, try to unplug and replug and still read CHK USB and the amp doesn't work.
Thanks for your answers
I updated it another time using the "Windows firmware update utility" instead of "firmware update in browser".
Everything's back to normal
