Comment (by stargatefan):
attaching sb800 specific documentation on enabling usb controllers during
reset. Pages 34-39. Found some interesting things in there and I didn't
see any of these implementations in the haiku source. Could be I don't
know it very well however or I could be looking in the wrong places.
According to the doc there there are a few specific setup procedures that
must be followed to get the ehci ports up afte tht ephy events and irq
enumeration. I will poke around for the sb600 and sb700 docs to go with
these.if anything its just more errata for the archives.
hope its helpful
