It would, as that's expected behaviour, isn't a problem, is a feature. As described above.The same count increment issue seems to be occurring with the RPi Debug Probe.
My 'dmesg' shows a new USB device number 46 ...
Code:

Simply an incorrect expectation, which doesn't match with reality.The expectation, possibly a naive one, was that unplugging the RPiDP, after the first time it was plugged in, would have decremented the USB count by one (1) .
Perhaps you need to explain exactly what you mean by "USB count". Do you mean "device number" as above or something else ?
