A year and a half ago, I wrote up a post lamenting the problems caused by counterfeit USB to serial adapter chips.
One of the primary issues was the inability to tell the adapters apart on the USB device tree when hooked up to the same computer. (There were, of course, other problems.)

ISR Stack Usage on mbed

Here are some notes on the things I’ve had to figure out by reading the source.
