It's having problems with the connected hub device. Is this 100% reproduceable or just from time to time? Does the hub really have it's own power supply as it claims? Please retry with a USB_DEBUG kernel - in case of a broken device the probing may take serveral minutes - maybe we should give some output without USB_DEBUG too in this case. > uhci1: <VIA 83C572 USB controller> port 0xc400-0xc41f irq 10 at device 7.3 on pci0 This is another controller. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
