a.) changes to USBEHCD.SYS to make it work with Intel ICH6 controllers.

b.) changes to USBUHCD.SYS for the same reason

c.) minor changes to USBOHCD.SYS

d.) IMPORTANT: changes to USBD.SYS. version 10.162 has a fundamental design

flaw that prevents it from handling devices that return configuration data >

1024 bytes. In practice, many USB 2.0 web cams have > 1024 bytes of

configuration data.
