I tried to upgraded my SX66 system and radio rom. When I clicked "next" on the Blue Angel Flash ROM Tool to start up upgrade, the pocket pc screen turned off and my desktop was diconnected with the pocket PC (activeSyn showed "Not connected". And the desktop showed up the message "Cannot recognize USB device". I took a look at the PPC, its backlight was off and only had a message "USB v2.07" showed up". I tried to reset the PPC, but it is not working anymore, only show the message "serial v2.07". Any one help please!!!
