> #2 is actually a really big deal with developing software to interact with anything USB. Well, I should say anything based on the FTDI chipset. I don't have any experience with anything else. Which is increasingly the case, given the modern proliferation of hobbyest hardware projects. There are no connection status events.

This is more of a Virtual Serial Port driver issue than an USB issue, right? USB itself always seems pretty good about connect/disconnect events (at least on Linux). However, the FTDI drivers which detect this don't have any way to pass it back to devices reading the COM port (because of RS-232 legacy, as you said).

However, for real USB devices (not FTDI/VCOM), connection event notifications shouldn't really be an issue. Yes, annoying to deal with, but at least you can detect it, unlike with serial...

RS-232 has signals for device detection, but they are optional.

Which still makes it a bit of a mystery why you wouldn't emulate them, since USB plug/unplug maps 1:1 to that signal.
