I'm up to pre7-6 and I'm still getting the bulk_msg: timeouts. The root
hub doesn't prooduce an error by itself (I'm seeing what I assume is a
normal startup), but I can plug in an IntelliMouse or a QuickCam and
produce the following error:
May 7 18:42:27 magus kernel: usb.c: USB new device connect, assigned
device number 2
May 7 18:42:30 magus kernel: usb_control/bulk_msg: timeout
May 7 18:42:42 magus last message repeated 4 times
May 7 18:42:42 magus kernel: usb.c: USB device not responding, giving
up (error=-110)
May 7 18:42:42 magus kernel: usb.c: USB disconnect on device -1
In the case of the mouse, I can tell it gets power (the red lights come
on) until the disconnect. Then power shuts off.
Might it still have something to do with my machine's many IRQ 9's?
/proc/interrupts looks all right, but I'm still not seeing any
/proc/bus/usb/* files. I've included my /proc/pci and /proc/interrupts
for perusal. Here's the (seemingly flawless) startup sequence from
/var/log/messages:

2.2.14 doesn't seem to have this reused IRQ problem. Then again, when
I tried the backpatch, it complained about not finding an IRQ for my USB
card at all.
All help is appreciated.
