* Rick Macklem, rick@snowhite.cis.uoguelph.ca

|
* Caveats: The driver currently uses spltty(), but doesn't use any

* generic tty code. It could use splmse() (that only masks off the
|
|
* bus mouse interrupt, but that would require hacking in i386/isa/icu.s.
|
|
* (This may be worth the effort, since the Logitech generates 30/60
