svn commit: r186808 - head/sys/dev/usb

[Edward Tomasz Napierala]

Author: trasz
Date: Tue Jan  6 09:03:02 2009
New Revision: 186808
URL: http://svn.freebsd.org/changeset/base/186808

Log:
  Add workaround for Parallels 4.0.  Without it, ehci and uhci drivers
  would fail to attach due to unsupported USB revision.  It should have
  no effect when running on a real hardware.
