Is there any work at all on usb2 isochronous transfer functionality?

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/usb/ehci.c?rev=1.14.2.10&content-type=text/x-cvsweb-markup

 * 1) The EHCI driver lacks support for isochronous transfers, so
 *    devices using them don't work.

Any hints on what's needed to make it work?

Seems DVB-S receiver cards use usb2-isoc mode, therefore the need.
