I think you are misinterpeting. The log you quote is from a successful attachment and it gets to show that that USB port itself does work, I elided the rest of the attach message as it's not really interesting or relevant (hence the ellipsis). The device in question fails with uhub1: port 1, set config at addr 18 failed uhub1: autoconfiguration error: device problem, disabling port 1 and that is *all* I get from the kernel, there're not even the vendor/device id reported. -uwe
