In the BIOS ("Award" is the name, if anyone's familiar with it) I have the
option to enable or disable the HC for the USB controller, and I have the
ability to enable or disable the assignment of an IRQ to USB, but NOT pick
which one.
Disabling USB via either or both of these methods (HC on/off, IRQ assignment
on/off) will allow the machine to boot normally. It says something to the
effect of "device not found"...not surprising, since I have disabled the
device. Re-enabling it causes Kudzu to pop up.
With the HC enabled and IRQ assignment on, the machine hangs at the line
"loading usb-uhci..."
With the HC enabled and IRQ assignment off, the machine boots. dmesg says it
found a USB controller with no IRQ assigned to it. Here is the relevant
section:
---

- I have tried removing and re-adding USB via Kudzu, no luck.
- I have tried freeing up an IRQ by disabling the modem and the game port,
neither of which I use, no luck.
- I have tried using uhci and usb-ohci instead of usb-uhci, no luck.
One thing I thought was odd: further googling revealed several references to
/proc/interrupts. I checked mine, and there is no entry for usb:
CPU0
0: 387990 XT-PIC timer
1: 36 XT-PIC keyboard
2: 0 XT-PIC cascade
8: 1 XT-PIC rtc
10: 415 XT-PIC wlan0
12: 6403 XT-PIC PS/2 Mouse
14: 8980 XT-PIC ide0
15: 857 XT-PIC ide1
NMI: 0
ERR: 0
Shouldn't there be an entry for usb-uhci in here?

Just to eliminate the (remote) possibility, I restored the default
configuration for the wireless card and it didn't make any difference.
Thanks for any and all suggestions!
