[SOLVED]How can I disable ehci_hcd kernel module?

How can I disable ehci_hcd kernel module loading?

I have up to date archlinux.
I tried add 'modprobe -r ehci_hcd' to '/etc/rc.local' but this broke net-profiles - ppp connection at bootup(I have USB modem (which of course work with uhci_hcd module) connected).
I also tried with '/etc/modprobe.d/modprobe.conf' and 'blacklist ehci_hcd' but ehci_hcd still loading at bootup.

Re: [SOLVED]How can I disable ehci_hcd kernel module?

Thanks, but:
1) blacklist module in /etc/rc.conf not work:

MOD_AUTOLOAD="yes"
#MOD_BLACKLIST=() #deprecated
MODULES=(floppy !snd-pcsp !ehci_hcd)

2) this not work also:

MOD_AUTOLOAD="no"
#MOD_BLACKLIST=() #deprecated
MODULES=(long_long_list_of_modules_without_ehci_hcd)

I found solution:
1) comments 2 lines in /etc/modprobe.d/usb-load-ehci-first.conf

#install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install ohci_hcd $CMDLINE_OPTS
#install uhci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install uhci_hcd $CMDLINE_OPTS

2) and blacklist module ehci_hcd in /etc/rc.conf.
