Yea, I've done all that.  I've plugged it into every bus (including one
that was USB2 ehci) by itself.  No fix.  Though USB2 by itself did increase
time to lockup some.  The specifics on the other chip:

# lspci | grep AS | grep USB
08:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host
Controller

Asus advertises "Asus USB 3.0 Turbo" ... so perhaps that A on the end
denotes some Asus funniness in the chipset.  The majority of the external
USB3 ports are from the ASMedia chip.
