Probably not unrelated. I have one of those Cypress-based hubs; it's nice except for the heat/power, which precludes using them in bus-powered mode with a laptop (or anything) ... I don't much like wall-warts! It might be too much to expect that when that hub's upstream port is suspended, its power usage goes to something reasonable. ------------------------------------------------------------------------- Take Surveys.
