Hello,
It turned out that the fault was the USB cable, i.e. the cable which
comes with the FR was somehow broken and stopped working. Other USB
cables are working fine. The broken cable still was charging the FR,
though;
Are there any known issues with the FR USB cable? How is the best way to
measure the connection in the cable to see which line is causing the
fault? I'm just wanting to know, even it's cheaper to buy a new one :-)
Thx
