I am working on qemu source code to provide extra functionality of
emulating virtual usb. Can I get any  documentation for the qemu source
code that helps me in implementing this?

The docs in source code and in the docs/ folder are what you get, more
or less. It will be a quicker process for you if you ask specific
questions about the codebase.

What types of docs are you looking for, for instance, or what you are
trying to accomplish.

I want yo add extra functionality of booting from virtual USB through qemu.
I need to write a new block of code in /hw/USB to emulate virtual USB. I
don't have any clue of how to procced. Code documentation of other devices
like hub network would help us understanding and implementing usb

QEMU already has support for emulating USB devices. What is it
specifically that the existing code doesn't provide and you want to add?

I want to write a new virtual USB code and boot from USB by attaching at
command line. This functionality exists for hard drive CDROM network
devices but not for USB right. If it exists can you please tell me
directory path for code ?

Infact emulation of virtual USB already exists. I want to add functionality
of booting from USB. Can you refer which source files to llok on and
modify.

Booting is the job of the BIOS that is running inside the guest, so you
won't find this code in QEMU, but in SeaBIOS. As it happens, SeaBIOS
also already supports booting from USB and it works just fine for me.
