Re: USB Issue K3S

It's possible that it's not just cable length, it could just be movement of the cable and proximity to 'something' else.
I've had intermittent issues with USB disappearing and I know for sure that at least twice it happened just after I reached over the back of the K3S to check a different connector.
My 'cure' so far has been to unplug the USB connector on the back of the rig and re-plug it, whilst watching the Device Manager display on the PC it's connected to. I have an extension lead on the USB cable and unplugging it there and re-plugging has no effect. Re-booting the PC has no effect. Of course it could be that something is not quite 'seated' in the K3S, but as all other I/O works 100% reliably, I have my doubts. As I have a mess of cables behind the K3S, I suspect some form of mutual coupling, which gets disturbed when I reach over. I guess I should try some ferrites.
I'm taking chances by writing this, as it's not happened for some time, so I better watch out when I next switch on. :-D
