So I'm very new to USB (using 2.0) and I'm still working my way through various application notes and the official USB spec. Currently I'm working with the ATmega8U2 as my controller. In one of the AN that I worked through AN_146 USB Hardware Design Guidelines for FTDI ICs and it showed the following schematic
So my question is: what is RESET#, and does it hold the entire MCU in a "wait state" until it detects a USB connection? My main concern is the possibility The MCU will only work when a USB in connected to it, because this MCU needs to do more than just handle the USB Data logging.
Thanks for any feedback/advice. If you know of any great resources for implementing a USB Data logging application I'd appreciate some additional references/sources
