Libusb/Usb/IP

Hi, I am proficient in using a raspberry pi. I have: created C++ applications; cross compiled kernels; attached wifi modules; turned into an access point; attached different wireless communication modules. I am aware of the different kernels, raspberry pi devices, and memory storage choices. I have used eMMC interfaces on the Compute Module 3 and on a development board. I have written bash scripts and made them run upon boot up. Is the USB device automatically recognized? Does it require special boot up sequence? Will the raspberry pi supply the power to the USB device? I would need more information to adjust my time frame. Thank you for your time, Dominik Sobota
