The USB key works fine on an EPIA system running DSL Linux, and also 
under Windows with the freeware ext2 fs driver.  So I think the drive

You would think that the powered hub would take care of the power issue.

Also, LinuxBIOS+payload doesn't seem to have any problems while loading 
the kernel + initrd from the device.
