Hi,
Does linux control hardware polling? If yes, then
recompile the kernel with USB as a module and don't
'modprobe usb' until it's needed. Afterwards, you can
unload USB.
I don't know the answer to my question but have
assumed this is how things work. It'd be good to have
a definitive insite. Anyone?
Warning; I've got my new hardware so ignorant
questions forthcoming. :)

Just a quick question. After installing Redhat 8,
I'm a bit concerned by the
follwing line in my /proc/interrupts:
10: 476 XT-PIC usb-uhci, usb-uhci,
EMU10K1
Aside from the extreme nausea resulting from
learning that my sacred MIDI port
is being put in the same office as the disgusting
mundane usb port, is this
a performance issue if I'm not actually using the
usb port?
I suspect there is a bit of a hit because the
interrupt handler now has to
poll all the sources, but I maybe not - I understand
the principles of
interrupt handling but not the specifics of the PCI
bus or the linux kernel.
So do I need to do something about this, or not?
