cold boot starts into pogoplug, warm boot into debian

i have connected two usb devices to my dockstar.
the first one is an usb stick with debian on it and the second one is an usb enclosure with an sata hard disk.
if i do a cold boot, the usb stick does not seem to be recognized, so debian doesn't start but pogoplug.
of course if the usb enclosure isn't connected during the cold boot, booting into debian on the usb stick always works.
it also works if i do a reboot (aka warm boot).
so the usb enclosure seems to prevent the dockstar from booting of the usb stick.
i already have installed the latest uboot from 30/8 and also the "scan all usb devices"-script.
but it doesn't seem to work.
what is the problem here?
how can i make the dockstar boot into debian even with the enclosure connected?
