--- Comment #12 from Alan Stern (stern@rowland.harvard.edu) ---
Yes, that procedure should prevent the driver from being loaded, except that
the module you want to affect is ehci-pci, not ehci-hcd.
You load the driver manually by doing:
insmod /lib/modules/$(uname -r)/kernel/drivers/usb/host/ehci-pci.ko
Using modprobe won't work when you have blacklisted the driver. Also, make
sure your .config has:
CONFIG_USB_EHCI_PCI=m
so that the driver is built as a module.
(An alternate approach, that doesn't involve blacklisting, is to simply rename
the driver file. Then modprobe won't be able to find and load it. But of
course you still have to rebuild the initrd image.)
