Getting Debug Information for USB

[lonnietc]

Hi All,

I am working with NRE and NOVA to learn as well as to maybe move some things forward. Right now I am investigating what it might take to write up a USB driver so that the code can see modern USB keyboards and mouse events.

This is a challenge, since I am really trying to figure out where to start and am spending a LOT of time reading and learning the code.

To that end, I am wondering if there is some way to get back some debug information while the system is running under QEMU perhaps so that I can see what is being sent to find out more about the USB.

I am also searching for a use bare metal USB library that might be useful so if you have any suggestions then please let me know.
Thanks and have a great day
