     As Brooks has said: there can be problems with running a newer
kernel with an older world (userland).  I don't know if USB will be
affected, but it's possible, as you will be using an older usbd.

     Some notes on this:

* See LINT for the various options that can be set.

* Setting "options USB_DEBUG" compiles debugging code into the kernel,
  but does not enable it.  To enable it, you have to write a C program
  that calls the USB_SETDEBUG ioctl() (see sys/dev/usb/usb.c).

* You could try setting "options UMASS_DEBUG", as this might give you
  enough information.  Note that this option, unlike USB_DEBUG, both
  compiles in debug code *AND* enables it.

     On a side note, are you using the uhci or ohci device?  I'm using
uhci without any problems, and I've heard that the ohci driver isn't as
good as the uhci one.
