Not followed current development state. I think you managed to get high speed hubs working now. Another traditional show stopper was the reprobe of devices when ehci took over control for ports that their companion controller already had probed plus a few drivers that panic and devices with broken firmware that hang if catched at the wrong time. Even if everything with the reprobe works fine - things take much longer to boot - probing USB devices is a slow story right now and take around a second per device. It can easily delay booting for Minutes on systems with lots of USB devices. -- B.Walter BWCT http://www.bwct.de bernd_at_bwct.de info_at_bwct.deReceived on Wed Mar 16 2005 - 13:07:12 UTC
