Re: [9fans] usb ohci support arrives -- caution

[Richard Miller]

Be careful about installing this update.  The kernel changes don't
just add ohci support; they also change the ctl interface to /dev/usb
(even for uhci) which is used by the usb daemon and other commands
in /bin/usb.  The change has been made in a way which is neither
forward nor backward compatible -- the new usbd won't work with
old kernels, and the new kernel won't work with the old usbd.
At present the /bin/usb binaries on sources have been updated but
the kernel binaries haven't.  So anyone with uhci usb who does
a replica/pull today will also need to rebuild their kernels.
