2.5.4[3-5] usb problems

[Matthew Harrell]

A few different problems.  First, when I use my USB hub then I get this 

  drivers/usb/core/hub.c: new USB device 00:11.2-1, assigned address 2
  drivers/usb/core/hub.c: USB hub found at 1
  drivers/usb/core/hub.c: 9 ports detected
  drivers/usb/core/hub.c: new USB device 00:11.2-1.4, assigned address 3
  drivers/usb/core/hub.c: USB hub found at 1.4
  drivers/usb/core/hub.c: 3 ports detected
  drivers/usb/core/hub.c: new USB device 00:11.2-1.7, assigned address 4
  drivers/usb/core/hub.c: new USB device 00:11.2-1.8, assigned address 5
  drivers/usb/input/hid-core.c: ctrl urb status -32 received
  drivers/usb/input/hid-core.c: usb_submit_urb(ctrl) failed

and none of the USB devices show up at all.  But, when I plug the keyboard
and mouse in without the hub they work fine.

For background I'm using a MAC USB keyboard (w/passive hub) and a Logitech
Trackball plugged into the keyboard.  When I plug the keyboard into the 
computer then both work fine.  When I unplug them I get 

  drivers/usb/core/usb.c: USB disconnect on device 2
  drivers/usb/core/usb.c: USB disconnect on device 3
  drivers/usb/core/usb.c: USB disconnect on device 4

and subsequent plugins of the devices get 

  drivers/usb/core/hub.c: new USB device 00:11.2-1, assigned address 5
  drivers/usb/core/hub.c: new USB device 00:11.2-1, assigned address 6

but the devices never work.

Finally, I've noticed a few times that the mouse has taken a vacation - i.e.
I move it and nothing happens.  This goes on for about twenty seconds and then
all the movements in did in the interum start happening.  During this twenty
seconds my built-in PS/2 mouse works fine.  Oh, and I get no kernel output 
from any of this.

My config can be found here

Let me know if there's any other information I can provide

More on this problem - it's not a time issue.  It's happened three more times
and I noticed that the mouse suddenly started working when I hit keys (any key)
on the USB keyboard.  And it starts up working by executing everything I did 
to the mouse in the interum

I'm seeing some strange USB hub issues here too (hubs that work fine on
2.4, not working on 2.5, hubs that only work on boot, but not attaching
later), so you aren't alone.

It's time now for some serious USB debugging to get on, now that we have
the main feature freeze done.
