[I don't know if this is a bug or a misconfiguration of my kernel.]

It seems that something is not reacting to USB interrupts as it should be.
I've connected an
aue0: Admtek Inc. USB to 10/100TX       , rev 1.10/1.01, addr 2
to my USB but performance is more than bad. A traceroute to www.freebsd.org
shows what's wrong:

It seems to me that the device is polled once a second instead of generating
interrupts.

Nick, our USB guru will know if this is a generic 
USB problem or not. 
If not please assign the PR to wpaul who is the aue maintainer.

UHCI controllers don't do polling. I have the feeling that this must be a watchdog timeout.

Achim,

do you still have the USB problem described in the problem
report with FreeBSD 5.2 or -CURRENT?

Mail to Originator bounces.  PR is far too old and many things 
have changed in USB since then.  It is very likely that problem 
has been fixed.
