The thing that gets me is that I have, what seems to be, two controllers
on my laptop, each with two ports. Does this seem a little excessive?
Is the hardware maybe not detected right?
This is the output from dmesg:

Does this seem OK?
I have two instances of usb-uhci on irq 9 (from /proc/interrupts)
9: 1 XT-PIC usb-uhci, usb-uhci
It doesn't seem to increase after the initial add/remove action (ripping
out the mouse)
Is there anyway to disable the controller at 0x1300 with the kernel? Ie
make usb-uhci only attach itself to the first one it finds and then
cease and dissist?
TIA,
Xander
