USB2 transaction translator

[Jean-Yves Moulin <jym%eileo.net@localhost>]

Hi everybody,

I'm trying to use an uaudio(4) device on a sheevaplug. My problem is about 
full-speed device connected to high-speed hub:

ehci0: error opening low/full speed isoc endpoint.
ehci0: a low/full speed device is attached to a USB2 hub, and transaction 
translations are not yet supported.
ehci0: reattach the device to the root hub instead.

And my computer doesn't have an ohci or uhci hub (for usb-1.1)... It has only a 
ehci (usb-2) hub. 

Do you know a solution for this ?

Or is there somebody working on transaction translator for ehci ? (this is in a 
TODO list in /usr/src/sys/dev/usb/ehci.c)

If not,  I will try by myself but it seems a bit complicated :-)


thanks
