USB Modules
 
I'm trying to do some "tuning up" on my Slackware installation. I notice this:
Code:
root@shilo:~# lsmod |grep hci
ohci_hcd              15172  0
ehci_hcd              24196  0
uhci_hcd              28048  0
usbcore                92316  5 ohci_hcd,ehci_hcd,uhci_hcd
Am I right in thinking I only need one of these? Then, of course, the next question is... Which one? I have the old USB1.1, if it makes a difference.

All of this gets loaded by hotplug, so I'm guessing that the easiest way to quit loading these modules is to recompile my kernel. OK, that's nowhere near as easy a using the hotplug blacklist, but kernel compiling is fun.
:)

Will leaving the modules I don't need out result in any performance gains?

Try to rmmod some of these, isolating those you need.

Duh. That's simple. Sometimes I miss the most obvious solutions.

Thanks, Linux.tar.gz
