Не цепляется внешний USB хаб

здравия желаю, собственно трабл такой.. подключаю внешний юсб хаб mobileData UH-12... в результате питание на хаб идёт (моргает подсветка на нём и подключенная мобила начинает заряжаться), но в системе подключаемые устройства не определяются... в dmesg после подключения выводится такое:

собственно, помогите разобраться в чём конкретно косяк. заранее спасибо.

P.S. ochi/echi и usbfs включены в ядро как *, ядро 2.6.29-gentoo-r1. На ноуте с 23м ядром и аналогичным конфигом хаб работает нормально. всё определяется.
