I run most of the secondary kit on USB and don't have a problem, which
is why I was a little surprised to be told that products were being
dropped because of the problems with USB. I'll have to disagree on the
durability of the USB connectors as I have no end of trouble where kit
is plugged and unpluged! PICKIT programmer for example is something
which would support that there are problems with USB, but where kit is
left plugged in I don't have a problem ...

No way I'll reply on any wireless connection where machine control is
involved. We used to use wireless keyboard and mouse, but currently I
get a 5% drop out rate on anything wireless. I have to monitor the
wireless network hubs and switch channels when BT switch every local hub
to the channel I'm currently using. Running two hubs on different
channels gives a more reliable connection on the tablets and phones, but
invariably downloads will crash because of a drop-out unless I leave the
device by the hub!

I've got bluetooth modules for the new DRO interface, but these suffer
the same problems. There are too many people stuffed into to narrow a
bandwidth even out here in a rural location. I had to stop doing EMC
testing simply because th background hash made it impossible where as 30
years ago I had nothing across the entire field.
