Subject: [9fans] OHCI USB support
Date: Tue, 2 Aug 2005 17:09:12 -0700 [thread overview]
Message-ID: <3e1162e60508021709604dce15@mail.gmail.com> (raw)
I've started looking at getting OHCI support into Plan 9.
I've noticed that when my kernel loads it detects my OHCI controllers
but it doesn't seem to do anything with them.
I started looking into the source and I found "usb.h" defines things
like Class(csp) ((csp)&0xff)
is 0xff the base class for UHCI? The base for OHCI is 0x0c.
If my assumption is correct then it looks like usb.h needs to be
rewritten to be more USB controller agnostic.
Anyone have any corrections to the above or insights to help me out?
Dave
