strange umass/scsi behaviour

[John Hay]

Hi,

Does anyone have an idea why the umass/scsi code behave differently
between if you boot with a device already plugged in as opposed to
plugging it in later? In my case it is a Sandisk Cruiser. If I plug
it in before booting, it works just great, but if I plug it in later,
it does not want to work.

Below is the dmesg output of the various stages.
