It looks like that the hubd driver doesn't remove the storage child after it is removed. It should be related with the warning in the dmesg ((ehci1): Unrecoverable USB Hardware Error). The error seems to be caused by the DMA transfer. Did you see the similar warning info for your Nokia N96 mentioned in your last mail? What is the output of prtconf -D?
