You're using usb-uhci, not uhci. If you're bored, it could be worth the
effort to try the uhci driver as well, but the code that handles
interrupts is similar enough that I don't think it'll make a difference.

If you do try, can you cut and paste the portion of the log (dmesg) when
you plug in a device?

I was looking for the brand and model of the laptop in particular. :)

Are there any strange messages about IRQ's or PCI in dmesg?
