Well none of that worked. My BIOS wont let me disable the PS/2 ports. The
ums device doesn't show up in the vmstat -i listing, and disabling acpi
(which also disables HTT for me) doesn't result in any improvement. Maybe
there is more hope of fixing the device probe on PS/2 than fixing USB
performance? At least for right now.
