USB host controllers on a server that does not use USB devices?

2013-03-20 Thread Anton Shterenlikht
This is on an ia64 server.

Do I need these devices in kernel:

device  ehci# EHCI host controller
device  ohci# OHCI PCI-USB interface
device  uhci# UHCI PCI-USB interface

if I don't ever attach any usb devices to it?

Thanks

Anton

Probably not on a server, but there are some built-in
devices in some notebooks (webcam  bluetooth)
that are run through a usb bus.

usbconfig(8) may be helpful.

It happened to me to see an internal USB tape drive, connected to an USB 
port on the motherboard.
