comment Which Multimeter is correct?
Have you got both of them connected at the same time? That will probably cause this.

What do you mean by "first"?

comment Switching USB connections between two devices?
Using simple BJT transistors to switch USB will not work, because it's bidirectional. The DPDT relay will probably work, especially if the cables are kept shorter than the 5m max. The switch IC will also work, although you probably want one that isn't in a tiny 2x2.8mm package.

.. but then it's your board and your responsibility.

comment Why are evaluation/development boards banned from being used in products?
I suspect product liability; it's the same reason that Java has that huge disclaimer about what applications you're not supposed to use it for.

comment What is the precise use of a memory controller and RAM latency?
Note that usually the memory controller is a subsystem on the same physical chip as the CPU.

comment How can a CPU (Core) begin executing binary code stored on die using silicon gated transistors
Why are you asking about "standard transistors" but specifically excluding mask rom? I think the answer is probably 'yes', but the question is phrased so strangely.

comment Small bluetooth device (not off the shelf) which sends a single button input to a phone
Apparently they just send a keyboard command: stackoverflow.com/questions/26741854/… - it might be easier to remap that in software.

Given your habit of asking the same question at intervals of a few months and ignoring or not understanding the answers, I think you need to learn more about computer architecture.

comment Difference between medical device status: CE mark versus FDA approval
Exactly what it means varies between product categories. Devices are supposed to have a "statement of conformity" listing which standards they are claimed to conform to which you can then look up on etsi.org , but there's a huge mountain of documentation there.

comment Difference between medical device status: CE mark versus FDA approval
Yes, CE markings do not say anything about effectiveness. For radio devices there is some certification that the device functions in the presence of interference.
