The patch doesn't fix anything.  The point was to gather enough 
information to figure out what's going wrong.  Without the debug 
messages, there's no information.

Perhaps things will slow down less if you change the new ohci_info() 
calls in the patch to ohci_dbg().  Or perhaps you can increase the 
timeout values in capture-example.c.

You should also apply this patch (be sure to enable CONFIG_USB_DEBUG):

It probably won't make any difference, but including it anyway is
worthwhile.
