On the other hand, if that line of code triggered this,
then power cycling the disk couldn't work. The ohci module
would need reinitialization. How did "-58" happen then?

p.s. The normal sequence of events there: OHCI sees something
on the order of a bus error, then gives a Unrecoverable
Error (UE) interrupt, and "disabled" is set. Recovery
is manual: rmmod usb-ohci, modprobe usb-ohci works.
