Depends on the application - personally, I'd argue that doing anything to put USB on any SBUS SPARC box is not an effort anyone would undertake for anything other than self-education...

As for the speed of such a theoretical application, it depends on what the original poster needs - a USB keybaord/mouse wouldn't need anything higher than 230Kb/sec, IMHO.

Don't confuse "possible" with "useful" - it was a throw-away observation that USB <-> Serial adapters might work both ways... Nothing more.
