Status of high-speed usb drivers

[Davon Shire]

Hello,
  I want to start this email saying I'm a very devoted FreeBSD user.
I've been using it a very long time. Did the subscription thing. Etc etc

  That said, I'd very much like to know where on the horizon do USB 2.0
highspeed drivers sit? I've seen that current is now into 6.0 but from what
I've read USB functionality is not even on the agenda.

  In my research I've noted that Freebsd got it's usb driver code from 
NetBSD
but that isochronous and high-speed functionality are not currently 
implimented.
I've asked about it now for more than 2 years with rarely a reply more 
insightful or
relevent than . 'Do you have ehci driver loaded? You can't use the 
highspeed without
it.'
  Please anyone within sight of my email, please give me and the rest of 
our Freebsd users
some idea of when this will be working or what's holding it up. I  even 
voluntered my time and skills to work on this problem if someone would 
reply and heard nothing.
  Linux has High-Speed USB, Windows has High-Speed USB, I'd very much 
like to use this
connectivity.

Thank you for your time and efforts on everything.

Davon
