No, doing usbdevs in a shell (is that what you meant?) doesn't show
anything either.  (It does, of course after re-insertion.)

More symptoms:
- the detection of the usb drive after adding to fstab was a fluke. 
The next few boots it was missing again...
- I have seen the usb mouse and printer appear at boot twice now; each
time after changing boot parameters (boot verbose, boot with ACPI). 
The usb key appear every time(?)
- when the usb mouse is not found there is a 30sec delay after
detecting the keyboard and before the message about failure to
allocate an IRQ for psm0 (no surprise, there's nothing there.)

I am now reinstalling from scratch (not that far back:-)

Cheers, Peter
