Hurrm, thats really odd... Esp since it does this in both hubs regardless of load. And now i get: usb 2-1: new full speed USB device using address 5 usb 2-1: device not accepting address 5, error -110 How about some better error reporting? =) -- Ian Kumlien <pomac () vapor ! com> -- http://pomac.netswarm.net
