comment How to identify the type of a microcontroller?
Note that microcontrollers ship entirely blank - NO firmware - and the software you write for them is called firmware. This seems to be part of the confusion.

Right. That particular demand (know what it is) is basically impossible, although precise timing measurement will enable you to spot it running faster. However microcontrollers can have read protection on the firmware as a very effective anti reverse engineering method.

Other way round: you can't run software on the device without already knowing what architecture it is and building the software appropriately.

Root access is meaningless on microcontrollers. Realistically either it identifies itself (some equivalent of user-agent in your protocol) or you look at the label.

If you can get hold of a PS/2 mouse or a serial mouse it would be much easier.

comment Why not use audio codec chip as measurement ADC/DAC?
Bandwidth limitations? Input impedance? DC accuracy & linearity? These may be fine for your project, but also worth checking in the datasheets.

"Mobile-terminated data calls" are possible, or you could use an SMS as a notification.

comment How does USB superspeed electrical signaling work?
USB 1/2 is I believe terminated with a resistor network that biases it to ground. There must be termination resistors somewhere not shown.

It's quite a clever circuit, but the designer really ought to have specified what voltage should be applied!

I think you might get a better answer from chemistry.se, although it's not off-topic here.

It doesn't say "5k" anywhere in that diagram ...
