It doesn't bring down the whole USB subsystem. You are overreacting to the volume of messages in the system log. All that went down was the high-speed hub -- but of course when the hub went down it took along the various devices plugged into it. > About a year ago i had a whole tree of Hubs, HDDs and Gembird > power-switches (4 switchable ports per device), after my tree reached > about 40 HDDs(*) the whole tree went unstable and i tought that it maybe > just didn't scale so i abandoned the idea. There should also be a > mail-thread from me from that time around! It's not a question of stability. The protocols and drivers are quite stable. The problem is that some of the hardware doesn't work as well as it should. In this case, the hardware in your hub isn't working right.
