Code reference for the new USB stack and its device drivers

[Hans Petter Selasky]

Hi,

I have just compiled a code reference for the new USB stack and device 
drivers.

http://www.turbocat.net/~hselasky/usb4bsd/dev_new_usb.pdf

Old USB stack:

http://www.leidinger.net/FreeBSD/src_docs/dev_usb.pdf

For example:

Compare "ehci_softc" in the new and the old USB stack. 

Compare "usbd_xfer" in the new and the old USB stack. 

Compare "axe_softc" in the new and the old USB stack. 

Anyone that can analyze the graphs?
