Like lsusb will tell me all USB devices. But now let's say I have modules that are loading USB drivers or high level USB drivers. How to find that list.

Look at the driver names provided by "lsusb -tv"

Same question for PCI

Look at the driver names provided by 'lspci -v' For more information like this, check out the free online, if not very old, book, "Linux Kernel in a Nutshell". Hope this helps, greg k-h
