I've installed all of the ehci patches from mm. My audio works from
the USB 2.0 hub now. But I am having trouble with the card numbering
of my ALSA devices not being stable on each boot.
I'm getting this in my log dozens of times, not sure what it means.

It is, but it makes none of the timing decisions itself. This

That's not the problem; it has trouble scheduling the bandw

That's a pretty bad scheduler if it can't schedule a single 12Mb
device on a 480Mb hub.
Well known issue; the 'stock' ehci scheduler is not efficient enough
using hub TT bandwidth to allow many audio devices to work through a
2.0 hub.
The -mm kernel series has a new, experimental scheduler in testing for
eventual mainline deployment that should allow all full-speed (USB
1.1) devices
I have a Philips PSC805 USB audio device which has been working fine
for several years on a USB 1.0 hub. I bought a new 2.0 hub and can't
get it working.
Here's a trace form plugging it in and they trying to play something.
All that is plugged into the USB 2.0 hub is a USB 1.0 keyboard and the
