Just disabling it (it's in "block devices" kernel config) as Richard mentioned should solve this. You definately want usb- storage here, bringing up a SCSI compatibility layer. The disk will then be recognized as sda instead of uba. CPU usage should drop because the driver handles the timing issues in a different way, I think.
