Yes, I've seen that, but only if I use "uhci". Please use
"usb-uhci" (or "usb-ohci"). In theory, the UHCI driver should not make
a difference, but it does. Don't ask me why.

Interesting. I'll try to look into that if I have 5min.

In theory, compiling things static or as module should not
make a difference, but somehow it does. Another USB mystery.

That's really a USB problem. Even if the irda-usb driver was
evil and doing ugly things, the USB subsystem should never let this
interfer with other USB devices.
Could you post your problem to the USB mailing list ?
