I tried the same thing with a problem I'm having. The command should be:

/sbin/rmmod ehci-hcd

This did half the trick for me!

My USB storage can be mounted now, so I have my backup disk available
again (which is great!). I still do not know why the notebook
automatically recognises it.

Unfortunatelly my scanner is still not yet working, with the ehci
drivers the scanner gets recognized but the whole thing freezes, with
the ohci driver the scanner is not recognized at all.

So, after doing /sbin/rmmod ehci-hcd I can access the USB harddisk, but
not the scanner. But even after removing the ehci module, the disk is
not recognized when I first try to start the scanner.

Weird. I'll have to try my scanner on my notebook. It seems to me that
not every piece of hardware (motherboard) is affected.

For my USB harddisk the reading when it works is:
