Description Hiroyuki Aizu 2001-10-23 17:10:00 UTC 
The USB Ethernet adoptor that use the aue driver didn't work with OHCI controller machine.
Because when any packet send to anywhere, aue driver try to transfer the data with set USBD_FORCE_SHORT_XFER flag on,
the OHCI driver failed handling 0 size packet.
The NetBSD's code was helpfull to solve this problem.

Fix: Apply following patch.
This fix  effective to both of -stable and -current, I think.
How-To-Repeat: Plug the aue USB Ethernet adoptor to the machine that have USB OHCI controller and send packet anywhere.

This is a not working case, nothing that breaks the machine.

Another report -- this patch (actually , I applied all of netbsd's ohci.c
1.75) fixed this for me.

However, i would get infinte looping of read errors after a while.  that
might be a separate bug, and this definitely fixes things from not working
to somewhat working for me.

This is implemented in CURRENT (the CURRENT code is pretty much in sync
with the NetBSD code).

That version should be backported to STABLE.
