This is one of the set:

/sys/dev/usb/ehci.c:
  revision 1.106
  date: 2005/11/20 14:27:25;  author: augustss;  state: Exp;  lines: +19 -12
  Keep a flag for each port that keeps track of if the port has been reset
  instead of having one flag for the controller.

  Also, don't try to modify read-only power bits if the controller doesn't
  support power cobntrol.

That at least gives the time.. and
usb/ehci.c
usb/ehcireg.h
usb/ehcivar.h
pci/ehci_pci.c

those were the files..

Cheers,
