Hi,

As a rule, Linux will be happier without it. Why do you want to enable it?

Have you tried adding "usb-handoff" to your kernel command line? That was added specifically to help work around BIOS bugs like those you've run into ...

As a rule, if BIOS bugs affect XP I'd not be surprised if to find them affecting Linux too.

That was interesting ... not directly related to USB, looks like maybe the "legacy" support didn't work very well either; maybe that's what the BIOS update was solving.
